the thing is this, i find if your serious enough that you have to still assign CONTROL groups with those keys then you probably shouldny be using the trainer in the first place, or if you do want to do this then the options that really interfere with these only have to be pressed once, so just press them and THEN start using the keys to assign the control groups, only key i dont agree with is the F10 key that brings up the menu but i hear its being changed so its all good.
Seriousness has got nothing to do with control gruops, they have been a part of the RTS genre eversince Red Alert came out on PC.
And frankly I just don't imagine playing any RTS game w\o them, why make it harder on myself?
Now what does all this have to do with using trainers?
