SOLO/CO-OP Improvements
Me and some of my friends love to play CO-OP vs advanced difficulty AI and have fun learning vehicles and such. Thing is that this gets super stale super fast and me personally I'm not good enough to have fun against real players. Would it be possible to make the SOLO/CO-OP mode more customizable? Like ability to do TDM, hardcore or limited time modes? Along with game modifiers like player HP, amount of lives/tickets/points, game duration length and such, naturally all modifying the amount of XP earned accordingly. This would make the vs AI games super fun in my opinion at least.
Portal.Battlefield.com
Battlefield Portal is what you want to use for this. If you put a password on your server you can even make it just for you and your friends. However you can only create your custom modes on a Internet Browser using that website.
Unfortunately you do earn way less XP (might not even be able to unlock new attachments) with Portal Mode than you do with normal Solo/Coop depending on how much you edit it.
