Maybe add some
a-tier Non-Donor 7 Damage / 6 Clip / x Delay*
and
a-tier Non Donor 9/10/11 Damage / 2 Clip / y Delay too?*
So to give some choice in what you could use, I feel like that is what's missing on FgunZ, some choice about delay / damage / clip size.
* a: Low/Mid/High (whatever seems reasonable), x: between 950 and 1100, y: between 1200 and 1400.
Might as well apply some damage / delay / clip options on other weapon types too.
