Overpower is the easiest to use. Those that say it's harder, I honestly don't know what you're doing during a pull.
Every time I am on another tank, my warrior instincts tell me to use my AOE, but they end up hitting nothing sometimes because it doesn't require a target to use.

While not the worst thing to adjust to and simply move an ilm closer to my target, the cone and target requirement of overpower is honestly worlds better when dashing in and needing to hit something. You have your circle AOE combo follow-up, so it's not like you CAN'T hit everything encircling you.

My suggestion would be to change all the other AOEs to cones. Keeping their combo as circles.
If they change overpower to a circle, it's honestly a nerf and yes I think WAR is a little too well kitted and OP right now, but this nerf is in the wrong spot.
