Couple of things I noticed while trying to run this, After killing Leoric and Maghda, it starts to teleport out straight away, and won't get any loot, also switching targeting from Maghda to her minions seems to be very slow and when there are 5 of those guys you could get 1-shot by their windup attacks (this hasn't happened to me yet, but I have over 1200 AR and 12000 armour on my rend barb and my WW barb is also very tank near 70k HP 600AR, 6000 Armour and overpower-crushing advance (35%dmg reduction) and it's been very close). Also on the ZK/Siegebreaker fight on my whirlwind barb, he starts just going for it immediately and never reaches 50 fury to go Wrath of the Berserker, and he usually dies when this happens, if he ever reaches 50 fury then he will kill ZK very quickly and be fine, but this only happens very rarely unless I intervene. The Ghom and Rakanoth fight goes perfectly for me though. Oh and I just noticed the bot open a portal and then TP to base, then walk back to Heretic's Abode, then TP again, just looping around and around, had over 20 Infernal machines so it wasn't that. All of my testing was done with my whirlwind barb and my rend barb on MP 3,4 and 5. Some of these are issues that might be useful to add as a tickbox in the next version of Unified trinity rather than your plugin, but as they seem to only be relevant here I thought this is where I'd post them.
Great work though, I'm excited what this will all do when you're done.
