Because profile software can be transfered, and be safer from any reinstalling, DCS crash ... And re-learning keymapping is easier. I got my profiles for each aircrafts/helos nearly the same, they have the same primary keys, like: Trigger for gun, Button A for weapon release, this for flap control, that for trim, radar cursor, lights ... etc. then the rest buttons have their own functions. I'm lazy, I don't want to remember much, you know. :megalol:
