Not sure if this is possible, but you could ask devs to change NA3 to battle mode on a certain day and have the 2v2s then. Just keep an admin around to make sure no one can randomly interfere with the duels. Strat is down for only so long though.
I thought Ravens had a private server? That's what it would take. Though nowadays any private server won't be XP linked.
+1 if you remember TX-Battle, the LLJK server, aka the best server cRPG ever saw. CHAOS and friends stomping LLJK all day every day.
Also that shitty swamp high grass map. Reminded me of the NJ meadowlands where I grew up. USA!
