I noticed that when pulling mobs from multiple rooms into one big group their pathing / aggro seems to get completely screwed up. I believe mob spawning may also need to be tweaked.
- Im continually getting multiple mobs per pull that de-aggro run back to their spawn point, only to return to the battle 10 seconds later (but now with full health)
- I've also been experiencing 1-2 mobs randomly spawning after I kill everything. A 2-3 room pull takes me 45sec-2min; which seems too late to be spawning as additional enemies, and a little early to be respawning. But maybe they're just respawning around 2 mins; which shouldn't be too much of a problem if the de-aggro issue is fixed.
