Hello Yuusuke,
I'm not sure if our server (S127-TONTON UK) is in your list or not but we are desperate for a merge soon.

1. Server ID - S127 - TonTon UK
2. GNW participation and group activity - GNW only 2 groups participates and 1 of them barely get 20 people. At most 18 and they always lose.
3. Sage World Battlefields status - Sage we do get around 15-30 people but not all the time. There were few times when we had about 21-22.
4. Average power - top 50 the average is about 25k Power & only 2 people has 40k+ Power.
5. Matsuri participation - there are days where some players cannot fight because not many people participates. And those who participates are mostly high powered players.
6. Ability to kill Kurama in the World Boss event - Depending if the top players are reviving but normally around 30mins

I hope you will consider our server merge soon as there are players who are thinking of quitting because of boredom. We desperately need at least -5-6 more groups from other servers to make it competitive. I think the more competitive the more players recharge to gain more power.

Thanks!
