I agree with the following:
It hardly takes that much time to press Q, click then Q again.
I never found it annoying. It only takes half a second to swap between your hand and your gun.
Seriously, if you think it's a problem, then you're really slow.
And if you don't like it, just make your own mini-game.
It's really simple.
1. Build.
2. Start server.
I would recommend making the server dedicated though.
And I suggest this add-on:
Default MiniGame (by McTwist)for two reasons.
1. EVERYONE joins the game when they spawn.
2. Yo can leave the mini-game/server and it won't shut down.
