well gee, thanks.
anyway, I have a one button macintosh mouse, which means primary fire is the mouse button and secondary is on the keyboard. I can't jump while secondary firing. Because of secondary fire and other essential keys being bound, my reload button is kind of hard to get to in a pinch. Thus, the grenade launcher is IMPOSSIBLE TO USE WITHOUT AUTO RELOAD. I either forget, try to reload on the fly and find it a total nuisance, or else I stupidly forget which I can't blame on anyone but myself, but for the most part the first happens. I fire the grenade, switch to another weapon to finish them off, then the next time I use the grenade I forget to reload and blow my chance. Forgive me for being a stupid newbie.
