There is a lot of stuff I would like to suggest for the next editor if there is one (Or for this if there will be any more DLC / Patches coming our way)
As one example the Modifiers - I would like to have the option to significantly increase the speed of the player and the vehicles, we already have the option to alter gravity and the height we jump but in my opinion I would like some quicker paced maps - the vehicles are still quite slow for anything crazy so I would hope that will make it next time into the modifiers.
Would also like a custom loadout so I could (as an example) put in a silenced Pistol / silenced shotgun and other weapons of my choice.
Add in the signature weapons from the single player game.
And a whole lot more stuff including siome fixes that appear missing from the current aditor.
