If i get hurt a little the bot uses a HOT, a little more a Direct heal, to much a COmplete heal
But typiclly when its time for him to cast CH im way way to low for it to heal me in time to live. If the dmg is coming in to rapid the bot will just go straight to a CH, and you die, my bot is geared out well and his Direct heals crit for more than a regular CH.
My bot never ever gets below 90% mana, and could cast direct heals/ fast heals all day long
The bots time where he makes the choice to use CH seems delayed, like the bot doesnt know what to do, fast heal, or ch, fast heal or ch, fast heal or ch, oh crap he is going to die, CH incoming lol

Taking out CH may save a lot of peoples lives, do the right thing! save a life
