Well, the pace is my own complaint, I'm sure some like it.
It's not hard to use the M6D Pistol. The fact that it has a scope makes it even worse, because it can be used as a improvised mid-range sniper.
The G2A2 Assault Rifle is just as annoying, as a short burst can easily kill you. You can easily kill several people with the G2A2, provided they don't kill you first.
