To be honest, a complete wipe could be fun. Then everyone is back to square 1. No more lvl 36 vs lvl 31 fights. And bring back the old exp system where reaching lvl 20 took 10 hours
In my opinion this would be even more hardcore for 'new players' or 'mediocre' to play againt pure nerdlingz. You know why?
Now almost everyone is on some sort of high level build(35lvl/36lvl/37lvl) so disparity is very LOW
(so playing 3 or 4 levels above/below median on server is not such a big deal)
BUT
if admins will wipe out and reset all players levels to 1, nerdlings(players who are playing every/every fucking day) will hit AGAIN
high levels very quickly leaving 'new players' even more behind than we have it nowadays (it's just my opnion, nothing will change anyway because crpg is f***ng brutal game
)
