honestly I felt like i spent 10 bucks on getting into a dead server. I logged in at 10pm pacific time and there was literally only 1 person in all of yaskers, and every low level area was empty. I played this game 4 years ago when there was still the thrill of low level pvp and getting different pvp gear and ranks. AT used to be nonstop guerrilla warfare... now you'd be lucky to find a cricket farting...
It's underpopulated yes, but you do have to realize it became significantly easier to level than 4 years ago. Even if the population was significantly better, you wouldn't see many players in low level zones, seeing how it takes about a week to hit level 70 the longest part of which is probably 65-70.
A zone like Asee Tep can be done in about an hour or less, especially that P2P has +30% experience rates by default, so they only reason you'd see actual low level PvP is when someone kept a low level reinc to gank others.
Low level PvP in Allods has not been a thrill for a few years now, no matter which server you're looking at.
