I tried checking, killed one expert demon, just one, and it stands at 9000th place so, 10000 active accounts is the limit I guess, if 5000 pp can be considered active. Sigh, this game is dying.
Thinking further: out of those 9000 accounts, assuming most player have 1 alt, then a lot of player have 2, then plenty have three, then some have an entire union just for themselves... I say 2000k actual player is closer to reality than their recent claim of 3million player.. that one's reaching for the sky and then beyond into yo momma's ass.
