It would be really helpful if we could edit classes in the lobby (outside of a match) so that we can set proper presets without a time constraint.

Many of us are wanting a solo shooting range so we can make loadouts and play around with firearms to practice.

There is no time constraint for you to do so while playing by the way, and currently there is no votekick feature so no one will votekick you "for being afk" while you make a loadout.
