Depends on the team I guess. Not if you have other support / Barriers / etc. The absorb is extremely valuable on 4* TF’s, for instance, and I’m usually seeing perma absorb bars on my team in that case.
 
	 
 
	EDIT: Also, since the other Nature buffs don’t stack, I save my Burnout for when I want to re-up Wild Bastion early. Just in case some mobs chew right through that absorb. Of course Burnout still gets used occasionally for a double Blizzard.
