Equilibrium can be a critical hit on HP recovery, it has saved me several times doing this in Alexander when the healer, "lagged out" or so they continue to claim.

With the new gear it isn't a minor increase in crit. The build goes from 775 Crit to 854 Crit for Warriors and up to 897 Crit for Dark Knights, without melds. More crit = more heal backs. This counts for paladin's Clemency too.
