Just to update some more info here, I already pre-seen that the gloves will be nerf and have a few backup builds that is equally fast without any of the shrines. And yes, with decent CD reduction, i can still spam breath of heaven. My point in the video should be pretty clear, the CD mechanic needs to be re-think, and breath of heaven doing both damage and healing at same time in a 50 yards that also travels through walls with no spirits cost just seems too over power to me.
If it is overpowered. It will get nerfed. This is a really early beta. 90% of the numbers you see in the game now will be reduced and fixed by the time it goes closed beta. And continued to be tuned til the release of the game. Not one build that is OP now will be on release.
