its too though man
first :they never fight each other
second:best in 1V1 or in party?
third:if best in 1v1 that makes no sense cause CZ is always party
so its impossible to find who are the best
so for the level(legit) is Zike from Diez and for skills in PK IN A PARTY I would say every top NP of serv with a good clan(refugee,Oblivion,antHillmob etc.)
