Ere we go is a really nice group utility. If u have speced in DPS tree and u have took Ere we goes again u can squeeze out extra 2000 (5x(200x2)) elemental dmg (usualy get mitigated to 2/3 of power) for ur party. Shaman alone can add extra 4000 (10x(200x2)) elemental dmg (many Order classes have ele resist really low) if timed correctly trought the Da Waagh is coming (oh I know, freaking bomb spec...great for Pragg tho

). So per one Ere we go rotation (10sec) u can do extra 6k dmg (theoriticaly). Yeah u have to slot a tactic, but there arent not enough good tactics for shammy anyway (Run Away is a must, ofc u slot Divine Fury and then u can slot Ere we goes again for premade fun or Hurst it doesn it for solo).
I dont understand why shamy inc HD is bad, ..becasue it aint DOT??? I dont really get it. Please elaborate.
@Sulorie
no its not, due to the low cost and insta cast. Its really good for burst.
well in 3-2-1 setup u only miss 2 (from 12) proc (and only if u have Chalice DoK, with Zealot u get the Marks so even the Zealot can synergy with DPS Ere we go burst), so aint that bad (if u spec DPS, if u go other way then its bad ofc).
Also u are right about mastery trees, DPS shammy usualy goes for Sticky feetz, Gork Barbz and Silence (dont remember the name) - all 3 in different trees.
