At least for Clan Arena.

At the moment we only have the choice of infinite ammo or the default amount. I suggest an option to choose an amount of ammo from 1-999 per weapon and perhaps even a toggle of infinite ammo per weapon.
Being able to set our own amounts would allow us to limit the ammo of spammable weapons while allowing more if not infinite amounts of more skillful weapons.

Changing the default 10 seconds of the round begin timer should also be an option (or at least a callvote), aswell as an option to disable Armour Decay.
