I don't know why this is but every time I hear you discuss MMOs I want to punch something.
Perhaps it's because you frequently get the mechanics of the games you're talking about just... wrong.
Mostly, I think it's because you maybe shouldn't be playing MMOs cause you don't seem to enjoy them.
Here's the reason MMOs don't explain every single detail of the game to you, they don't have to. Part of playing the game is learning how to play from the other players. If you're not learning from reading chat and asking questions and, yes, reading the wiki or even the manual then you're doing it wrong. You're cutting out a major portion of the game which is the other people running around you.
It's an MMO. It IS a social game. And if you think reading the wiki isn't social, who do you think wrote that wiki?
Not taking advantage of those other players is like... playing a console game with only one side of the controller. If we're going to make ridiculous analogies.
Oh and if you're worried that the game may be too daunting for the common mortal think of this, there's no manual or on screen instruction for the iPhone either but Apple seems to do fairly well selling and supporting those.
We live in the age of "figure it out or ask". Maybe that'll just have to be a problem for you.
