This feat seems rather lackluster. Most of the time you can't tell if it is doing anything at all. I realize that maybe the devs don't want to go crazy with player healing, but for this particular thing a lot of time is invested to get 3 stacks and it just doesn't seem very fun or impressive. I have 2 stacks of it currently, and it's so disappointing that I actually wish I had chosen something else like "Colors of the Queen". This would be much more worth it if you could actually see some healing without staring for a long period of time. Even if it were just 1hp a sec, that would be something. At least it would be noticeable that you are actually healing. Surely this can be improved.. to make it more fun, and more useful..
