What I'm getting at here is the capacity for very high burst damage from a single skill is not at all limited to Enhance. Fire is a great example, but there's also Destro chaos bolt, SMF execute, shadow devouring plague, 4 stack arcane missiles, etc.
The problem with windfury and shaman imbues in general is that they proc randomly based upon weapon attacks. We have no control over them. This leads to a fair bit of enhance damage being essentially passive; around 23% in T16 (not counting searing totem or searing flames). That's nothing compared to the reigning champion of passive damage, assassination rogues, at 39%. But it's still higher than I would like.
