Few things i wanna point out to the OP Mice mobs still very much run away when you WS and Fungar still counter you with the poison move when you hit them while they are inflated I did several test on this before the i started the summer event, So you should remove those from the list that is false information. I would love for more mob AI but the Eft aggro thing seemed more like a bug considering the nature of this game's release state than an game mechanic but idk.
