The mechanics aren't THAT changed -- the difference between Wrath and Cata isn't any more significant overall than the difference between Classic and Wrath. You still have a set of abilities on a button bar that cost mana/rage/focus/etc. and have cooldowns (either global or independent). You still want basically the same gear, just with the numbers changed around a little bit. You still want to stack basically the same stats. You still have talents, you just can't mix-and-match quite the same way, and the new talents are quite a bit more interesting than the old ones.

So yeah, the WORLD is changing dramatically, but basic gameplay still works like the same game you've always been playing.
