1) Immolate is always the top priority, it's a huge dps loss if it's not on the target (not to mention the amount of embers you'd loose). If manually controlling havoc then just ensure you've got plenty of time left on the Immolate before casting it.
2) It should only do that if the "cancel cast -> drain soul" option is ticked, otherwise it'll only use DS on the current target when < 20% HP.
3) This is already in there (it activates when the unit count in a 10 yard range from the target goes over the high AoE unit value). I'll make a change to improve the usage of it with Mannoroth's Fury though.
#1 - Ahh ok that shouldnt be too hard too track on one target, thing is if multi dotting is on, Do all Immolates then have a higher prio than saving Havoc stacks?
#2 - It tried too Drain soul all the time even when the option is turned off, ill try catch it in a log when i see it next.
#3 - I dont know what your high AoE count is doing but its not what i described xD, It goes about it all wrong, First it SB/SS Dots too the main target - Tries too apply the Seeds, Only problme here is that the DoTs are allready ticking because they wer placed first and the DoTs blow up the first Seed application which in turn blows up the second, So there now no Seeds and it tries too re apply seed constantly by spamming it at the target only too have them blow up because th Dots are still ticking, Gets stuck like that.
