Make a simple incentive to choose either side of Gauntlgrym by making armor/weapon design (purely cosmetic) only available on either side. And atleast lowering ad cost to switch to either but can only do once a month or remove ad cost entirely and can only switch once a month.
Actually the tooltip says: "On resurrection, You are shielded for 10% of your total hit points" If it is "shielded" this functionality was the invincibility that soulforged had before. Just speculation...
Now that Sunburst is " fixed". Recovery helps with AP gain so you might want to take that in to account too if you want to fire your dailies quickly. I have 4k with Rising hope...overkill?lol
