Building this game around the cross server shit is wrong.
It turns the game into a shit hole like Xbox Live. This 15%-buff is just flat out depressing. Its encourages people to run in smaller groups just to gain a sick dps bonus.
If heroics are too hard for 95% of the players like people are saying. Then blizzard did a good job for once. Heroics should need heros. Not 14 year old night elf hunters and feral druid rerolls.
