everybody's been thinking it: the wiki (in its current state) is in horrible shape
-many of the pages are incomplete (more red links than I care to see)
-it's weirdly organized at times, and there are a quite a few pages that could be combined/split/streamlined to be easier to use
-little info on content beyond T6
-sparse quest guides (half of them are on the forums)
-the class pages are basically useless, they should have info on how the class plays, basic pros and cons, notable spells, and where it fits into raiding.
deeper than these issues however, is what do we (as a community) want the wiki to be? is it supposed to be a resource or a strategy guide? is there to help you out or give you the answer?
at any rate, something needs to be done with the wiki. it seems our current options are to
1) open up editing so anyone (or at least registered forum users) can add/edit content without having to apply for privileged (people are lazy, it's true) or 2) hire an individual/team to gather community input and make the necessary changes (may have to pay them, but it would be worth it)
