Combo Fury is a fun mod that could synergize well with some non-meta weapons, but it suffers from two things: Its timer doesn't renew on another glaive kill, needs to completely run out. Secondary weapon requires a reload before it actually doubles the mag size. Yet the mag size instantly goes back to normal once the timer runs out. ...three things. If it instantly doubled the ammo and was renewable at any point, it would have been much better. It just feels too clumsy and awkward otherwise.
