i dont get how it helps to slowly heal when you have already taken 4500 damage. If you are still taking damage you are already in the hole and just getting deeper that really you need a direct heal or someone to grab aggro to prevent dying.
If you have lost aggro then meh 4500 in the hole doesnt matter a ton, sure its nice to have the hot kick in and not have to worry about healing.
I dont get how you find it useful tugela. I dont see the greater saftey margin, if im getting my butt kicked a HoT that kicks in when im already at 1/3 doesnt do much. If im not getting my butt kicked i dont need a heal.
