shamblers come first
i agree (but they are already coming first! sort of)
Now, a little thought about yetis
:
First, smth we all know: they need +HP, +dmg, less mana cost
Second: I propose that Wild swings are incorporated from the start(or from 2nd skill), so:
Yetis I/II/III/IV = +25% dmg (from wild swings)/ +50%dmg/+75%dmg/+75%dmg OR
+0%dmg/+25%dmg/+50%/+75% dmg from swings(to nearby target)
And there you go, sedna has aoe!
(also they could increse a bit the aoe dmg from Heal IV)
In addition, the currently WS should be change to smth like Thick Fur: giving yetis more armor, & smth more. Or it could be called Wild Animals (smth) which gives tham that thick fur=armor , and more dmg or critical strike chance. So think about it! 
Nature's Reckoning helps a sedna alot.
Yes it is. She and Oak should get it of generals(DJ), and UB & Rook assassins (it helps Rook against minion Ereb)
