Chimeron was easy when your basic heals hit for 10k.
It was a lot harder when when your basic heal didn't, so you had to have either expensive hots rolling on everyone, or be ready to spam like mad and hope your healers didn't pick the same dude.
that mechanic was the most strict breakpoint in the game: either you can heal 10k with the cheap heal, or you couldn't. Depends on how your gear went.
Feud damage was always manageable. The hard part was just getting splashed people from 1 to 10k before the next splash.
MASTERY STACKED SHAMANS GOOOO
