What Kind of Raid boss damage mechanic do you dislike the most? This applies to both sources and potential sources of dmg
Fire
Tank Swapping
Adds (tanked)
Cleaves & localized boss aoe
Debuffs
Chain lightning or meteor (non-split)
Random dmg spikes
Interupts
kiting
Other
Honestly I probably dislike random spike dmg the most like anub's frost orb.
