I have some interest in WoW but having never played it I'm rather intimidated and confused. I have questions.
1) Is there sensible solo progression with the story?
Explanation: I played Guild Wars 2 and I just started hitting these very strange grinds of repeating the same quests over and over to level into a safe range for the next zone. The whole time there was no story arc, just a general vibe about the condition of the area I was in. I had to do this because the story leveling went WAY FAST and kept outpacing my character.
You'll find that the quests are a little samey in terms of what you have to do, but in
storyline terms, each zone has a reasonably well-designed continual plotline that leads to a climax when you're done with the zone. I'm not sure how levelling speed actually is for a new player who isn't drowned in heirlooms (items that you can hand from your high-level character to your low-level character to increase experience gains - unavailable for your first runthrough), I know some players tend to level faster than the zone pacing dictates but that might be down to heirlooms. Either way, if there's any mismatch in pacing, it's the story being *slower* than the rate you level.
3) How do the expansions work?
Explanation: It is my understanding that each pack has a new level cap. That gives me a very strange impression on say, if I started with WoD and then decided I wanted to go back to an old one. Would all the levels be super low for me? And do different packs limit what races you're allowed to use?
You're can only go through the expansions strictly linearly, but they're all bundled together these days with only the newest expansion being a separate purchase; you'd just want to purchase the Battlechest (which is everything
except Warlords), and that'll give you a consistent 1-90 experience. Then, when you're ready for 90-100, you can pick up Warlords. Purchasing Warlords alone is *not* sufficient; you need to go through the content in order.
(Strictly speaking, Warlords does grant you a free boost of a single character to level 90, so you *could* buy the Battlechest and Warlords and then jump straight to 90 and the Warlords content. I don't think that's a good idea for your first character, though. Either way, you can't do it without the Battlechest)
4) Do patches affect all expansions at once?
Explanation: I hear people saying how questing/leveling in MoP was super slow but in WoD it's a lot better paced. Well is that sort of adjustment something that goes back on the others retroactively, or are the older expansions not necessarily past their issues when better things come along?
Expansions aren't independent games, they are bolted on to the existing game, and in
real terms all they dictate is
how much of the game you can access. Hence, a patch affects the entire game.
5) Can you reasonably develop solo as a healer or is it a pain in the ass apart form a group because they are weaklings?
Explanation: It's a really common problem in RPGs, and I would rather approach a group already being worth a shit.
Healers *can* deal adequate damage these days and can indeed level solo, although it's still beneficial to group up. Alternatively, every class has three specs (Except those crazy druids, with four), and every healing class has alternative damage-dealing specs if you'd prefer to swap to an out-and-out damage dealer rather than levelling directly as a healer.
