If I get undead in a NM after the patch its now 50/50 whether I win or lose depending on purely the AI unit comp.
The change to the flee mechanic is great but the AP cost of each unit should be increased. I just fought with my 1720 AP, a 5 HI, 3 LI, 1 LIA, and 2 Archers undead army that now has a good number of rare and a few epic items on.
Even with good flanking from my LIA and my archers doing some damage on approach 5 HI, plus 4 more melee units will overwhelm and kill me regardless of tactics.
Maybe this is glitched and for some reason too many units are spawning but it is getting stupid....
