Well, I'd love to join, but I've put quite a bit of my coins towards my current Vietnamese-based group, and learned quite a bit of Group Skills in there. I read that when you change the group, you have to re-learn them, maybe? . Sadly, the two guys who are the leaders have been offline for a few days, which is a bit sad for me. I might still want to wait for them though.
I've seen you in the top of Nine Tails Invasion damage deal ranking, as well as most of the servers' leaderboards, I'm very impressed.
One thing I'm worried is that 50 contribution points/day is a bit high for my taste :P :P
Yes, I'm quite active in the game, and my English is surely more than enough, currently level 41, look me up if you're interested: KazunariAkazaki
