Enemy behavior for some reason feels like it got downgraded from beta to full release. I distinctly remember enemies actually making an effort to go for my back line, ranged enemies occasionally going for my back line, or threaten my ranged characters standing too close to my front line.
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.
