Ok they are technically a buff to players but it amounts to a nerf to the instance. Guilds have had a few weeks to down Arthas, and many have done so. Fire and Blood hasn't gotten very far into P2 yet. I'm actually in favor if this. I like the fights to be challenging. Blizzard wants them to be accessible. This way eveyone's at least somewhat happy. The hardcore get the exclusivity for a while, and eventually the more casual get to win too. I'd have preferred another couple of weeks before they implemented this, but you can't have everything. I'm also not sure that I like being able to click the buff off. I understand the desire, but will there be away to determine who beat it unbuffed vs. buffed? I can see the progression arguments already.
Also Blizzard has released a lot of info on Cataclysm stat changes. The conservative in me dislikes them on principle, but I'll take a wait and see approach. I'm just not liking a complete rework of the Enhancement class mechanics again.

Here is the big one for us
If you are a melee DPS class, druid tank, or hunter, expect to see:
•A lot more Stamina. Bear-form Stamina scaling will be lowered as a result.
•Strength if you wear plate. Agility if you wear mail or leather.
•Existing Attack Power becomes Agility and Stamina.Armor Penetration becomes Haste or Crit.
•No Intellect on melee gear. Hunters won’t need Intellect since they will no longer use mana. Shaman and Retribution paladins will get mana and spell damage in other ways.
The other ways is going to be interesting to see what they come up with. Right now i blow through mana like nobodies business. I oom a lot in 5 mans when aside from bosses everything dies to fast to use SR effectively.
