Holding LMB makes it harder to stop firing right before it overheats though, and as far as I can tell, there's a longer waiting period if you overheat.
Moving passive skills is a real good idea though.
So? All that means is that you will have to learn to let go of the button sooner. If you're paying attention it's not a big deal, if you're not, you'll overheat anyway. I'm not saying to change the actual fire rate, I'd just prefer to not have to click every single time.
