I've quit this game last few weeks but I did play 1year after many breaks.
I've seen the good players some average amps that may be best in other aspects like pvp dgs or overall as a player, so here's my top picks(in my own opinion):
DK: Dopknight
Whendy
Stuns
Shaman: xxdeaathxx
Mahdik(dk if its spelt right)
Trumpstyx
Rogues: (many active old players before left the game so quite hard to choose good rogues to date)
Haten(bit inactive and outdated)
Barb: Pvpfroze
Inar
Cristianoi
Necro: Negativism(inactive and gone shit but one of the beast before)
Warlock: I see many dick names but they aren't the best lol
Reaperlock idk his new ign but he's lvl20 atm
Lennojx
Paladin : Gladiatoor
(We've got many +10 paladins right now like chamba but they aren't skilled as glad so)
Mage: Skynete (definitely op so hes right to be on top)
Aladdeen
Urgoits
Priest: I've not seen much priests on cave nor arena. But I'm sure there's quite op out there
Behappy
Bladedancer: Swagathero
Myouren
Ikanuzz
Druid: xshammy
Dozy
Ranger: Alejanbro
I can name many old ones but yea it is intended for active players :)
