I would like to see some upgrade on the new Tactical AI (As per the frog asking for new tactics).
When one melee unit goes into combat, the rest with movement enough to reach atleast the same unit as the first one, should engage in combat, everything else is a waste of an enemy team not going all in for the victory (especially when I have counter attack, and the 3 wolves IM fighting attacks me 1 at a time)
When creatures cast spells, they should move around a bit, spiders should close in, then use WEB.
Edit: When a spider has webbed an opponent, or another monster have debuffed something with say, curse (turn based debuffs), the monsters should try to reach the front-line to start combat, or save the curse spell until just before combat (2-4 tiles away, depending on everyone's movement)
(moved the idea into its separate idea as an edit)
It should try to defend weaker units, if a group have 1 very strong defender, and 2 weak units, they should try to move in the strong defender type in front, and the 2 weaker units 1 square behind it, as to be more protected.
The AI should change targets if a more favourable target is within 2 squares of where they are (so they move 1 square, and then attack).
More may come later, if you have any situations where you think the AI is moving in silly ways, please bring them up. And sorry if Frog is feeling attacked, I only mean to post these as.... leaks in the tactical combat UI. I know it can be hard to reach all the details so I am trying to put a post together so we do the information gathering so you can focus your time more on what you think needs tested 
Sincerely
