Hey man, if it's time, it's time, and I'd never try to convince somebody to stay doing something they don't want to. However, I do think you are being pretty rash if you're making your final decision based on 2 days with a patch that Blizzard has said over and over will be unbalanced and disjoint for a while.

You can't compare this with pre BC/LK, because there have been major talent tree revamps and class changes, especially around the paladin. I haven't played yet, so I have no idea what it's like, but I'm sure they aren't going to leave paly tanks unable to hold agro and getting two shot by heroic mobs if that really is what's happening.

And it could be that we just have to adapt. Let's face it, castrandom/castsequence has really made our jobs easy. We might just have to undo that style of play and learn another, maybe even harder, style to keep going forward. But hey, that challenge can be fun as well.

Anyway, hope you stay and at least give the actually expansion a shot, but if you don't, bon chance.
