1) New server for this gamemode or eu_crpg4 as a variant, eu_crpg5 for siege.
2) 2 thematic teams by the random for every new map. One of those: european, saracens, mongolean, russians, turks, japans, nords etc. There are a lot of items on every taste in crpg.
3) All items divide on nationals. You can take all items from your team national even you don't buy it in the shop.
4) If you have heirloom item you use it instead of common.
5) Balance, repair, money, exp, multi as in common battle mode.
6) As an option you can check on crpg.net which nation your character prefer and it's take into account when balance divides players by teams.
I think it's good for roleplay for factions and simple players. And this gamemode involved players who prefer native m&b battles.
P.S. Sorry for my english i hope you understand what i mean )
