prob around 400-450, but now before patch prob less as most ppl log in only for domi
1-2guilds per side that do highter dificulity raids/heroics
about p2p, ppl moved to rus p2p, as thers much more ppl
This game is dead, but it's still nice singleplayer game, i recomend start9jg new zones you missed, thay will bring you some fun, thay even made some jumping puzzle
for 450ppl it's hard for new/backing ppl to be motivated inaf to solo start from 0 to be decent at bg whos main activity in this game but prob you not gona have problem finidng party for basic content as most content need only 6-12ppl
So if your planing back for short duration and checking whats new, i can recomend 100%
for longer duration you will need catch up alot cash shop by grinding, or top up to stay decent, but not competetive as most veterans got around full cash shop, until you plan spend 600-1k euro, or farm around 50k-100k bc
