Eh my philosophy is if something is the best at a certain job, then use it that way. The only competition in rest stalling that Early Bird Khan has is from Harvest Lum (waaay too many weaknesses to stall) and Shed Skin Scrafty (much lower life but makes up for it with 35 more base defensive stats).
And yes, I'm really do like those with a niche... if it crossed your mind.
