Holding the Flamer right click blocks changeing weapon (reload)
others (most idk if any other are effekted) let you cancel animations to switch weapons so it also should not block it
the animation for activating secondary fire block switching weapons (if the botten is hold)
blocking switching during reload:
1.hold right click the full time
2.start reload
3.try to switch weapon but it wont switch untill the full reload and alt fire is active
4.(if right click is releast it will no longer block switching weapons)
just normal switching is also effekted:
1.hold right click the full time
2.spam Q
3.notice a delay between switching the flamer and any other weapon switching
(this delay is not present on any other weapon)
Reaload blocking:
