Q:
Combo Effects and AH
I believe it does. I know when you take the might from justice use trait you get 3 stacks of might and get healed for each one. I dont see why it would be any different for the combo field might stacks.

I know for sure AH proccs if you trigger a combofield that you placed yourself. Hallowed ground heals for 3*AH (3 might) when you trigger it with mighty blow and SoP heals for 1*AH, 1 retalition.
If you have friends in the field they all give you heals for each boon you trigger.
I assume it works the same with other people combofields but tbh i never paid attention to that and just taken it for granted.
The cool thing with hallowed ground is that it heals for 1AH per ally each second. Trait master of consecrations and place it in the center of a zergclash and its probably one of our best skills. Add in 3*rune of water and 3*monk, 20 points in virtues for more uptime and ranged placement of consecration and 20% more uptime on boons (total of 70%) from food and you can stack stability on your team like nothing else in the game.
Pretty much every boon you can apply will heal you as long as it applies to an ally.
