I'm pleased with it for the most part, although a few things need work IMO.
1.) RN. We talk about this lackluster skill every day, I won't waste my time talking about it too. We all know the story by now.
2.) Make alacrity more desirable for us. 'Medic' epics/gear in general all have the stat on and yet it doesn't affect our 'main' type of healing (yes, I said it. HoTs) Either have it have an effect on the ticking time between HoTs, or maybe lower the GCD. No need for both, but 1 of them would be welcome.
3.) Shield Probe. This is a little personal thing here, but I'd love to be able to Shield other people. Probably through a talent so it's not a total cookie-cutter copy of Sorc-bubble, if that wasn't possible maybe increase all healing DONE by the op when he has Probe activated, would give us a micro-cooldown and help out with some of those sticky situations.
4.)Diagnostic Scan. Castable while moving, that's all.
Can't think of any more right now...
