Raiding is always fun, especially when you are learning a new boss (Naxx). However, when your guild turns competitive and hardcore, it could be exhausting and of course, burn out few raiders. For me, I stopped WoW because I felt that its like an obligation or responsibility for me to log in every night to raid, for if I miss the raid I won't be able to get attendance and DKP. Raid is getting too competitive and often enough people blame each other when a wipe occurs (especially on farm bosses).

But overall, raiding is all the time fun and enjoyable.

P/s knumskul : Yeap MC and ZG is getting plain and boring. C'Thun and certain Naxx fight is superb.
