I made that point in A Call for Cooldowns
Part of the problem, I believe, is that multiple Squaddies can stack skills like Rally, which create a not-quite-infinite loop - or at least keep 1 Soldier running long enough to find the Maguffin and end the Mission in 1 or 2 turns. So I’m starting to believe that there should be a quite severe limit on the number of times a Skill can be used in a particular turn - or on a particular individual.
Most of these Skills are fine on their own, it’s when they stack that they become OP.
Can’t see how a team nerf would work on RB at all, though, since it’s an individual skill.
