I’ve only ever seen a boomkin at top damage once and he was literally just running around like a madman dotting everyone up - He was insanely geared too so I can’t imagine the dot ticks but the kb/death ratio didn’t do him much justice.
I’m rolling with UH DK at the moment – I put out more dmg overall than what I do in frost and enemy healers really dislike me :P Last night alone I’d have had a 60+ killstreak (over numerous different bg’s) if it hadn’t have been for 3 deaths in EOTS from hunter/druid/ele knockbacks off a cliff
Personal preferences for solo play would definitely be either DK, mage or hunter for solo play although strong arguments for spriest and druid (2 classes which I’ve not played for a long while cause I’m lazy)
