At least as important is the +4 damage from morale. Erebus and Oak, can each get maybe 15 minions without much trouble, and max out at more. At the 15 minion level the total is +60 damage. With a maximum of four yetis and six minions from totems, Sedna never gets more than +40 for each point of morale, and has a good deal more trouble even maintaining that number of minions. The same arithmetic goes for QoT.
Don't forget that Shamblers and Yetis do AoE damage, it follows to reason that their single target damage would be lower. I think in general Yetis would be a much more valid skill if you didn't have to wait for level 15 for Wild Swings. They should just incorporate that into the standard skill itself the way Shamblers function and then replace it with an appropriate level 15 skill.
The other effects of morale are either percentages, or are in my opinion not as significant ot this issue, but I believe morale is one of the main reasons Generals with larger numbers of weaker minions are seen more frequently with minions builds.
Morale seems to me like any other skill really in that it needn't be identical from DG to DG. I realize that would be a bit of a design philosophy change, but with generals I think it'd be appropriate.
So with Sedna already bordeline OP, the need for buffing just doesnt seem like a priority.
Bear in mind any point spent on Yetis is a point not spent on one of her other powerful abilities. Buffing Yetis doesn't necessarily mean making Sedna more powerful relative to other DGs.
