So we basically just do it whenever both teams have enough players? I guess that sounds plausible. Actually, when we first came up with the idea, I thought that we would just have a few rivalry rounds per war, all of which would be long, hardcore, anything-goes rounds. I didn't think that we'd be doing it for every type of game that we typically play. Either that, or a rivalry war, where the entire event is just one long OHS round. Ever since I found this one epic location, I've been wanting to host a war like that, but I decided to wait until we have at least 20 (10vs10) players who reliably show up to community wars. Unfortunately I think we're a long way off from that, but I'm thinking of maybe doing one with less people at a smaller location like Onteora Lake or something. Still, we'd probably need at least 5 or 6 serious players per team.
Whoops, forgive me for going off on a tangent. But yeah, I guess we can just not do rivalry rounds until each team has enough players. I think we should also say that one team cannot have too high a number advantage over the other. We could say that the ratio of players on each team cannot be greater than 2:1. As far as skill imbalances go, I don't think that's as big a deal. When has a baseball or football game ever been called because one team isn't as good as the other? They'll get called if one team cannot scrape up enough players, but not if the skill level differs between the teams. I admit that I have seen some pretty brutal beatdowns when the teams' skill level is imbalanced (my brothers have played in Little League games where the scores are like 20 to zip), but this is water warfare. It's different than other sports in a way that even the most cunning veteran can be defeated by some kid in swim trunks who's just there because his friend dragged him into it. And as I said earlier, we could limit rivalry rounds to maybe only once or twice a war; they would be the hardcore rounds that everyone prepares months ahead of time for, while the rest of the war is just meant to be as fun as possible. I think this idea is worth considering.
Now, I think it's time to change around the Downpour schedule a bit... Heck, maybe I'll even redo the whole thing.
