Not really, no.
We currently get enough avoidance straight from gear, and if your threat is fine, there isn't really much point not to stack stamina (Naturally gearing for fights - armor trinket for melee intensive fights etc. where applicable, /broken record)
Naturally, you only really need to stack stamina for heroic modes right now. Doesn't particularly matter what you do in normal modes.
