If there's a charge ability for Orkz, it should have them scream WAAAAAGH!! Because that way, when an entire horde is all using charge to close to melee combat faster, and all screaming WAAAAAAGH!! through your speakers, its going to have the trouser-browning effect on the poor sods in the front line that it should do.
You mean it won't be set to all the buttons as a secondary effect? How else am I going to faceroll the keyboard to the tune of yelling orks?
Could have to how Red Orchestra has their Russian charges and banzais to where you get enough people sprinting at the same time in a close vicinity it will activate.
