Tried it, I agree with Skilly here.
Before I flip tables, Mr McSic explain how the hell do you even add your skills during a TDM?
Do you expect everyone to sit their asses down and wait for you to add your upgrades during mid-fight?
Played about 50 rounds of AnD with the mode, I insist you bind a double-inputted command to add and even better, to check their current upgrades.
