MMO's have bugs. MMO's change. This has been true always with Wakfu as well, yet you are still here as well (at least on the forums). Plenty know how to play without raging including myself (though many of my RL friends speculate whether it is possible for me to ever get angry... I'm a lazy person and I find getting angry a waste of energy).
Personally I still love this game, bugs and all. Of course things could be better, but anything could always be better if you look around. Wakfu is still a unique game and you'll have a hard time finding another MMO like it.
It's quite easy to jump back into and even has a much better and quicker tutorial area to go through now for those that are new or just need a quick refresher.
I'm still always recommending people to play Wakfu for something different, fun and love turn based tactical games.
