Hi :)
I'm just lvl 21 at this point, and I have not yet used spells beyond a few app IIs, most are still app I. (getting new upgraded ones made by a friend but havent had a chance to use them yet)
I run out of power relatively fast if aggro gets on me and I have to do anything besides standing back and healing the group. (when aggro gets on me I promptly do everything I can to shake them and pull them to someone else in the group who can tank... most times I get them off me pretty quick but sometimes its a real problem) Other than those times that aggro gets on me, I really don't have any trouble at this point keeping everyone healed and things run pretty smoothly.
I use, like you, primarily Bloom and Regrowth during the encounter. I only use Sylvan in extreme cases when everyone needs to be healed at one time... and I do use the Minor arch healing in combination with Regrowth/Bloom on the MT to really boost his power bar back up to its maximum.
I know its not a 'heal' but I'll throw in there that I like to throw in the occasional Weakness and Feral Intimidation to help make the fight against kinda tough mobs/named and for my toughest encounters I try to use Subterfuge to slow the mob down.
I am looking forward to using my upgraded spells, app IV, to see what differences that will make in my technique and performance. If there's anything I should be doing differently, please let me know =)
