Dunno what making the Maple have slower ROF would do as it’s pretty much par for the course. Not opposed to it, but I don’t think it’s a very huge balance issue.
A weapon that I say needs to be looked at the most is… the Nykorev. I’ve made a post about it before, and basically it’s a Legendary tier hunk of junk. It has AR tier firerate, with SMG tier damage, with recoil that makes some of the most uncontrollable guns look tame.
Changing meds in that particular way… not really sure what the point of that is. There’s some meds like vitamins that only really exist to reduce toxicity. Even then, they’re scarce enough that when a player finds them all they manage to do is postpone death until you can find a vaccine, unless tipping point/above 50%. A more useful change to meds would be making the animations for most healing significantly slower, immobilizing, and heal over time. Being able to recover all lost health after 1.3 seconds while jumping around erratically is… unimpressive to say the least.
