I haven't been playing all that much during WOTLK and restarted boxing 5 just before Cata, never did any instance boxing and still in the process of lvling teams (3x 5 @60 now) but I still enjoy it. true there's a lot of gathering quests but tedious as they are, they give xp;-) Got 2 chars to 85 boxing quests and will now set of to lvl 1 more team (prob dk's) and after that I will start to lvl them all to 85 too.
I am looking forward to instancing with them and I read alot here about tactics and all, only thing I'm abit worried about is how to CC, gonna need to really get that right.

So all in all still enjoying it all
