Second Wind is a terrible ability and either needs redesigned or outright removed.

It can't heal more than 50% of baseline when it crits (that's they way crits work)

so let me get this straight...

your signature says "give healers something to do" which would be, I dont know.. healing... and yet you want to buff an ability so you dont have to heal?

yeah, we get it, you just want to dps more...
