6 second cooldown
Blizzard is going back to implementing the 6 second cooldown on both CoH and probably Wild Growth. They did say if shamans healing are preferred, they may (but probably won't) give CH a 6 second cooldown, or go back to none of them having cooldowns.

I don't think the 6 second cooldown is a good idea. The reason they said they are thinking about it is because they became 90% of the healers healing. Wild Growth is a 51point talent. Its like saying a hunter is using their 51 point talent way too much, so were going to increase the cooldown. I think it's silly.

why does blizz favor shamans so much
