"By default" means nothing. There's no point in you even bringing it up. We are discussing ASTs issues with going oom. In any fight where going oom for any healer is even an option, CD's like DS and procs like Freecure are going to go a LONG way and will get used often. Period. Don't act like Freecure is some rare proc either. It's a 15% chance on you main spam heal, and so much as 1 means savings of 800~ MP. All those CDs mean additional health restored at no additional mana cost. It doesn't have to be up 100% of the time to save you mana.
