U can't compare Celes to this. Although this server has perfect files it's still a russian server which a few months back was totally unknown for the rest of the world, and barely known in Russia judging by the nr. of online ppl they had and still have from Russia. At the other end, supreme (azure) which was the most famous l2 private server. It's not that hard to understand kids
Anyway, i'm pretty sure that all decent clans would want to play on this new server, there's nothing else coming that is even remotely good compared to this one. Problem is, they're afraid server will be a fail because of the administration here and they don't want to waste time playing here. Still a little over a month before the server will start, give it some time, many clans (from those that will play) will announce themselves in the last 2 weeks.
P.S. One thing's for sure, if administration won't improve the hardware until start server won't hold more then 2k people, thus, i sure hope to God that all that army of 20-30 ppl clans that was seen on Celes WON'T come here.
