Heya. This is not a QQ post, but merely my opinion on raiding in a casual-hardcore perspective.
First of all, I'm currently the guild master of a casual/hardcore guild with 10 bosses down. We're a big fat family and the community and atmosphere rocks, and we raid 3 days a week. I'm rolling a feral druid tank.
I've seen so many threads about how much raiding sucks in this expansion, I must from my perspective dissagree. Never before have I had as much fun raiding as I'm having while raiding.
One thing I really like is how we get to use all our spells in raids at the moment. Healers need to use all their healing spells, tanks really need to help out on stuff and DPSes must both kite, interupt and grant mobility for the raid.
You actually need to consider replacing certain people due to a certain class being better for respective encounter. Chimaeron once introduced us to healing focused encounters, and lots of bosses in there learn players who've recently began with WoW what stand in the fire is and stuff like that. If you are an experienced raider, you have to see through the easy encounters and realise that this tier is alot about learning for new players.
As a tank, no longer do we need to stand at one spot, taunt the boss back and forth and go AFK for a while because you know that noone overaggroes you. We have to move the boss properly, in many cases positioning is vital, and we can't always rely on our DPSers to do all the interupts.
As a healer, as mentioned before we get to use our whole spellbook to keep everyone up, and dispelling has been taken to a new level in offense to the "dispell dat curse" ideology.
As a DPS, kiting has become vital on most encounters. You often have to help out on healing in some way, and lots of stuff like that.
Second to that, I think the lore rocks, boss encounters are well designed and in general I love how Cata is being played.
This is the first tier of raiding but we've got so much potential comming in this expansion. Mysteries to solve and bosses to kill.
I personally love Cataclysm so far, and I hope you guys have the patience to let Cataclysm grow and become the best expansion so far.
Peace out.
