I'm ok with this new feature made by Jonne so we have to get used to it. So -1
The M4 is the most preferred long-range weapon in duels in any case. But, I guess it wouldn't do any damage to make an exception for weapon slot overlapping when it comes to duels, if players deem it awkward and annoying.
Yeah, M4 is the best for shooting you're enemy at duels and you can hurt them by crouch-shooting. You know that if we're stand-shooting, the shots you've released will spread throughout the player or around of the player. So, we don't have to make an objection about this update and new features added in this gamemode.
