I think my biggest annoyance with Barb in the second beta (my first time playing) I found I had to use the charge / rush attack to get any movement and as a regular attack, then the only real crowd control was the ground toss one - but you need rage so it's not always ready and even if you have rage you can generally only do it once. Eventually I added in the Jump which helps a tiny bit for crowds and also a bit more for movement, but it has a pretty slow timer. So my biggest complaint really with Barb was other than zooming around the screen to attack enemies it was hard to deal with crowds. Whirlwind I tried but it felt terrible, ran out super fast and did almost no damage. Overall it was fun to try Barb, but it didn't sell me much on the class again.
