Like I said, I did that already.
60 people online, 30 of them afk in Giran.
I have huge lags IG, as if this is a homemade server.
I also read this:
http://maxcheaters.com/forum/index.php?topic=279853.0
which I didn't like at all.
Imo, server is "too old" for someone to join.
No matter how much you keep on advertising it, it won't help it.
Have you considered of a wipe and a fresh start ?
This time without so many custom things like GoD armors (which I don't mind, but for some others it's a reason they don't join)
or masks with "extra skills".
Also do something with the lag.. 60 ppl on and it lags like hell in Giran. I also went to a farming spot- It was laggy there too.
