1024 players on Unity, I guess this is just an Asura problem.

They just have too many factions, and most of them are rubbish. 90% of people are on one of 3 so the others are wasted.

I've played other games with similar systems and they just did what I said previously, they have 3-4 factions and duplicate chat channels for each one. Even if chat channel 2 was manual entry from the unity menu it would be better.
