Class impressions!
Tried Thief for the first time today, and it's pretty fun. Settled on a massive glass cannon build with sword + pistol and shortbow. I started off with daggers (as per the "given" pvp build) but I wasn't feeling it. I can definitely see why people "spam" heartseeker; low cost, hard to miss with, does good damage (kinda). I found pistol whip to be a far better damage dealer though, and using the sword's teleport and immobilize makes it very reliable to hit with. Scorpion wire into pistol whip is also pretty sweet, makes me feel like the first boss in AC explorable, lol.
It was fun running around quickmatch trying to kill people. It's a very different playstyle than my Mesmer; this felt more active and less reactive, which is pretty cool.
I'm finding it hard to keep up with all of the options Thieves have available, though. With no cooldowns it really means you should be choosing the best skill for the best situation. That's something that's going to take some practice. There have also been a bunch of times where I accidentally mash a little bit and do 2 attacks in a row (if those two attacks are blinding shot or something? Congratulations you are out of initiative!). Cool class, and I like all the stealthing too. I'm not using poison very much, so I think I might see if I can spec out of it for something else. Not sure what that would be with my weapon combination, but I'm sure something will work.
Probably going to make a guardian sometime soon. Ultra tanky build is what I have in mind. I always hate fighting them in pvp, as mesmer or thief. Perhaps I can try being on the other side for once and figure out what is going on with them.
