ArenaNet just doesn't offer anything in replacement to the trinity. In order for someone to play 'support' as they'd like, they have to trait a very specific way, and pick the right armor out of a dozen different variations. And even then, their abilities will be situational, and likely AOEs that don't explain themselves very well to groups (I have to constantly be reminded to stay inside the white circle for healing rain). Or worse still, combat is too much of a shitstorm to actually plan out ArenaNet's alternative to the trinity: combofields.
I've never, ever seen combo field combat work like it did in the highly scripted class previews. In reality, it's it's cryptic and it isn't very effective (or just a random bonus in zergs).
My response is mostly about combo fields, but can be expanded on:
Game definitely throws you out into the world without so much as a "how do you do?" It elicits both frustration and community interaction. Had to tell a guy in [map] yesterday how to retrait.
Ask, ask, ask people. The bad news about GW2 is that it doesn't put a bullet to your head to talk to people, but the second people talk to each other, the moment they learn so much.
I mean, that's what people do. That's why stuff like reddit can be useful, since people link guides and specialty websites all the time. That's why the wiki will probably be one of man's best uses of the internet. Talk to each other.
So when you're out in the world and something confuses you, ask a question in map chat. No one answers? Then guild chat. It's the one thing about MMOs that should never be ignored. Otherwise, I'd play a single player game. There some that do a better job of simulating the feeling of being one of many silent people.
So, in the case of combo fields, if there's any field I don't know about, I ask about it. When I'm in a party in a dungeon, after a fight or two I start asking people about their builds, their fields, etc. People understanding what everyone can do automatically starts discussion on maximizing effectiveness. Well, as long as you aren't around people that believe there's only one or two good weapons/builds for each profession.

Anyway, story time.
The other day I was grabbed into a group with a few friends from another guild. The mission? Sorrow's Embrace, path 2. I've never set foot in that dungeon since doing the story, so I went in there blind on my Might-stacking Condition Charr Warrior. He was my first character as of the official release so he was the one I felt most comfortable with.
And that dungeon is hard. There are Dredge Bombers that throw out AoE bombs once a second that can stack burning on you. One of the first mini bosses can chain stun you in a corner with his bazooka. Then there's the fact that the dredge in general are great team players; they have AoE boon givers along with stunners that setup for quake attacks that will then take out a chunk of your health. And through the confusion, they have Excavators that tunnel over to you and knock you down, keeping you place for everyone to spike you.
But, our impromptu team never had a single person defeated. Most of the had a myriad of cripples and were tanky enough to keep the enemies clumped up without dying themselves. The elementalist and I constantly put out fire fields and stacked 20+ Might across the party. When one got low, they'd dash out while I'd burst with Sword for the immobilize. When I was in trouble, I'd always notice a water gush spring at my feet and would hold still, or even swap to my traited Longbow to add some regeneration to the rest of the party.
Overall, it was awesome. A few days later I went in again, did the same path, and wiped three times before we got through. I was probably the highest toughness player on the field, as we had two Thieves, a level 70 Guardian (I had Rabid exotics, he probably had rares at best), and a Warrior who I'm pretty sure was Berserker based. I am more than likely going to make my own Thief a stun build now.

Oh yeah, and my Guardian just reached level 80. I'm still not sure about where I want the Scepter build to go. The only option for me at this point is to spend time with him in PvP rather than WvW, because it's the only way I can maximise burning duration without shelling out several gold at once. What I will try doing, however, is taking out the points I put in Healing/Vitality. I'm going to try giving him rare Knight armor instead, focusing on Power/Precision and using the high Toughness to keep him from dying. I'm having a very, very hard time getting a decent burn duration on a single enemy, so unless I team up with someone I can't get all of the bonuses off of burning opponents to stay on consistently. This means I need to either go back to the 20/30/0/0/20 build I had before, or try a 10/30/X/0/10 build, with points in crit damage. For reference, currently I'm 10/30/0/20/10.
While that's happening, I want to start another character on the road to level 80. My options are as follows:
Level 55ish Sylvari Thief. He can't decide between condition spike build, a Signet of Malice Hybrid build, or a Stun-lock Hybrid build. I'm leaning on stun-lock, although it's going to be weird getting back to used to a Sword main hand.
Level 8 Charr Ranger. He was going to be WvW only, except for whatever reason all the juvenile creatures I used to find just don't seem to exist anymore. Perhaps I need to look harder, or they were taken out around release and I've just been imagining them. I don't know what I want to do with him. He'll either Longbow main and be a sniper/crit build, or he'll Greatsword main and be a close combat dodger. One thing I know for sure is that Rangers need their pets, so whatever I decide will be in part based on what pets I fall in love with.
Level 17 Human Mesmer. Mesmer was my favorite class in GW1, and the one I used the most during the betas. He fell by the wayside after BWE2 because of some of the nerfs, and me wanting to try out other classes before I fell in love with the new version of my third favorite class from GW1, Warrior. Second favorite was Paragon. As it is now, I've theory crafted some builds, but the traits and utilities never seem to add up the way I want to. I love the Mesmer's weapons; they all do different things in remarkably different ways. I just can't come up with a build that complements the weapons the way I want to play them. Which probably means I just need to get down in the dirt, figure out what problems I have, and just trait accordingly. I love Staff so much that I'm trying to focus on Scepter or Greatsword instead. Well, that, and I don't want to make another Rabid set after scrambling an exotic one for my Warrior.
Level 11 Asura Engineer. I want to try and play with turrets reminiscent to how I play Engineer in TF2. Failing that, I'll probably use my own derivative of this guy's build:

Level 10 Norn Elementalist. I'm actually not that interested in Elementalist. Will probably be a Staff build.
