I've tested the way the current cleric bot heals and it's exactly the way it was pre-update. It will immediately cast an HoT on a damaged group member (even pets, thank god!) and then it will PAUSE 6-8 seconds before deciding to cast any other heal on that same target. I've tested this numberous times and every time is the same result. HoT - LONG pause - CH - Short Pause - CH - LONG PAUSE - HoT - LONG PAUSE - CH - Short Pause - CH - repeat, repeat.
I think the best temporary way to fix this issue is simply to remove the HoT. I would much prefer the bot to simply chain cast CH with the target at 85% rather than sit there and do absolutely nothing for 80% of the fight, even though he has plenty of mana to do so! Removing the HoT would most likely clear up this problem.
