Have you informed the participants on how they should act during the 2vs1 , it shouldn't become a gangbang with no chance of winning , and the ''team'' should def not be allowed to connect 2 , 3 or 4 hits at once , it should be consider and treated as a FRIENDLY duel.
So take risks and use punishable attacks rather then only playing safe as much as possible
On a side note I would suggest adding another 5 ranks of corruption since these 5 can be obtained quite fast. We shouldn't all be able reach max rank in only a few weeks again.
Also the EoD offerings should only consist of EoDs earned through slaying invading SOVs instead of exterminating frogs in The Depths.
