I noticed this too - but between Beta 2 and 3. In 2 those flies and centipedes in the prologue would go straight for the back line, which seemed to be removed in beta 3, and full release.
The Brimorak fight was especially weird to me this time around. The breath weapon it opened up with only hit his allies... I think in the effort to change AI behavior based on difficulty settings, it may have broken them in turn-based.
Good thing I'm not really here for the combat, I guess. The party banter gives me life. Speaking of party banter...

Another exhibit in meaningful party banter, this time Seelah conversing with a quest NPC. I don't remember this being in the beta. Or at least it wasn't in beta 2.
