This app does not fit into Cheat / Bot / Hack category. Well its facilitating gameplay but I know a lot of people that use different macros since D3 vanila was released and noone of them got banned. Banning people using such app whould be retarded from D3 Devs, but actually they are pretty intelligent so they wont do it.
For example my actual situation. My left arm is broken and is fixed to my body, I have absolutelly no chance to press keyboard skill keys by my left hand, my mouse has only two side buttons. So what are my options? I can not play D3 for like one month or use software like this to help me play.
That's a BS excuse!!! I had a stroke over a year ago, leaving my left hand useless ever since! I haven't missed a day of playing because of it. Learn to use your mouse and assign skill keys to the buttons!
