I think the outdated info was on charge rate, where a value of ~71 gave you the fastest time between left-click and shot fired? This has since been patched though.
My dump stat is charge speed since the actual change in speed is minor (like .1-.2s IIRC?), and since ammo affects your clip size I like it maxed (also: major Weapon Specialist enjoyer). I also kinda like the charge delay as part of the plasmagun feel so it doesn’t bother me
