Here's one for the Misc. category:


In SP Arena combats, PC's should move into proper formation before fighting starts.
Why? - If you walk up to any regular fight, your party automatically moves into formation before the fighting starts. However, if you decide to accept a challenge to play in the arena, the game teleports you there into one big bunch perfect for the pre-positioned enemy to drop a bunch of AoE effects on you, putting you into an even bigger hole. There's no reason to do this.
Suggested Change: When starting an arena fight (in the single-player campaign, not the arena mode), characters will automatically move into the formation you set up BEFORE the fighting starts.


And back to Abilities for a moment:

Perseverance (on players) should passively restore some of both types of armor armor per turn
Why? - Currently, it only affects Knocked Down, Petrified, Stunned, and Frozen, and it only returns a slight amount of armor. There are so many other, more beneficial places to put the ability points. This should be altered to be useful for certain build.
Suggested Change: Perseverance will restore a fixed number somewhere in the range of 2 to 3.3% armor of both types per turn. So at level 1, you'll get 2.0-3.3% armor, but at level 10 Perseverance, you're up to 20-33% armor restored per turn. This sounds like a lot, but keep in mind that is 10 points which you are not spending on Warfare or any other damaging abilities, all it is doing is mitigating the damage you're taking.
