If you have good aim, anything is deadly my friend !
Doesn't matter what the damage is set to or your hp/ap
You can't change a style of play when someone else out aims you
You talk about changing Delays and such but can you actually aim yourself?
Are you trying to benefit yourself or are you just trying to force people to use these type of delays?
I, Myself however wouldn't like super high delays where I RS once then I get RS glitched but I don't like spamming shotguns either
Maybe you could change it so you can't spam but won't get RS glitched at the same time
