Allowing the ability to turn on Full Auto has been helpful with some weapons such as hand cannons, side arms, fusion rifles, and glaves. However I have also found that having that on has had some not so desirable effects. I have mostly noticed it with the new pulse rifle "revision zero" and some high RPM shotguns. Mainly, I cannot release the trigger button fast enough to not fire a second or third round. In this case, being able to choose a single weapon or weapon type to ignore Full Auto would help. For the most part I never want Full Auto on a shotgun.. Revision Zero is a more tricky one. In regular fire mode Full Auto is fine, but once I switch to the special fire mode, I may pull to fire one precision shot, but in the time it takes to pull and let go, two shots tend to be fired, with the second one being far off target. For that one gun, reducing the fire rate during Full Auto would help those who cannot let go fast enough, but allow those who can quick pull fast enough can still trigger, but for other weapons I am not sure the best solution other than allowing each weapon a toggle for Full Auto, and instead the current setting in the settings menu as a default for new weapons.
