Sorry if this has been suggested or addressed before.
In DOS1, we could clearly see if an action would cause other available actions lack action points.
To elaborate, let's say you have 2 skills that take 3 action points each and you have 5 action points available. When you hover over Skill A, the bottom right corner of Skill B would turn red, meaning that if you use Skill A, you wouldn't have enough AP for Skill B. Same would go for using 3 AP for moving; you'd see red triangles on bottom right corners of both Skill A and B.
Can we have it back pls, so we wouldn't have to check how many AP the next skill we plan to use would cost, before doing anything? =)
