He is kinda true actually, moradon got a pretty active merchant aswell now. Cz not being that active aint rly ppl's fault, if there would be better farming spots there as well as skills wouldn't cost 1 billion ++ (there is still alot of lvl 80 or above people w/o any skills opened and they rather just fishing atm), plenty of ppl would actually go there either for farming or for pk.
There could also be some kinda NP shop (either getting items with np itself, or getting an item for each kills that can be exchanged later for items [nothing fancy item wise, that'd make pker OP but smth that would motivate ppl to go there]) or whatever, there is plenty of things to do to create pk and force ppl going there.
They got a decent amount of ppl now, if they tweak CZ, making it a better place farming wise, making it easier / cheaper to open skills (putting back the old drop rate for lobo- shaula, etc when people almost 100% of the times got 1 quest item) as well as keeping a 3-4 days free starter exp prem rolling continously, the server can kinda easily become hella active.
W/o those it's hard, but when ppl see they can hit 80 during a free prem, and could also open skills w/o hardcore farming, they ll stay, just like a decent amount do during this event now aswell.
Main problem was and still is, is that it's debatable which is better, farming at CZ / BF, etc, or fishing with 1-2 chars (not even mentioning more chars). When smth like that is a question, CZ activity will suffer from it obviously.
