ESAR,

I think that would be an interesting way to get around it. I was thinking of what if when you selected an attack for battle regimen que, that it eats up that part of the stamina bar and does not let it recover while its up in que, allowing you to attack while who ever is initiating can time the actual BR. The problem with this idea lied with what if you wanted to stack buffs or debuffs before the attack? I think if the game had action queing it could solve that problem, but then the problem lies with what if the que went over the stamina limits and what happens to the recast timers of abilities in the que.

BR's aren't that hard to do, but they were definitely designed for a different pace of combat.
