This is a war game. Who cares if it's their busniss or not. Lol Pick you a side and start hitting is my guess. Or grab some alliance clans of your own and hit both sides lol.
Hit both sides? I feel like that would be a horrible idea considering most osw clans are in this osw and I can just see it ZAFT, WDGAF, Apoc, Og, UC, Warlor (think that's everyone lol) Vs. NR. Would it happen prolly not their is enough clans involved that they'd just allocate a different clan to it or run a few different. Asking to join in an alliance is kinda hard while an osw is happening makes it difficult.
Not trying to put you down or anything just hang back and find the family with similar ideas and operating procedures as you and you can also look at the reputation for the clans, alliances. Talk to leadership of those clans ect once you find one that you're interested in joining that is.
