Well since downtime is the price for healing good, I would love to see an action, you only really need to make one extra action, where you place a bet you can pull of a long cast time for a big payoff. You have your Glare and then a Glare Flare with 4-5 second cast time. So if you know you don't need to heal for a long time relatively, you can bet your downtime for a big cast that then goes off or not. You are punished for betting wrong by just being forced to cancel the casting if you need to move, someone needs to get patched up right now, etc. Well, just make it not work with swiftcast or lightspeed etc.
