Im using naga chroma 12buttons. its quite good for a slow keyboarder, but the thing is, if u in hurry to press, maybe a different skill will come out. LOL.
btw, im using only 3 buttons,
no 1 - Party mic
no 3 - Team mic
no 5 - Courier
the key is just too small for me to press, so need to gap those selected actions.
