the devs have said 1v1s wont be enabled, they disabled them because they felt the mod was not designed around 1v1's.
I doubt they will ever make 1v1s count again towards the war or veterancy, you can still play them with newbies to teach them how to play if you want. Or you can play someone for fun.
What does 2.0 have to do with making 1v1's count?
when have the dev's said that?
2.0 was said to have a ranking system like relic online
