If being seriosly why everyone from devs/admins ignored a real solution to fix this problem, and limit caps to SRP and/or official factions(use same mechanics as with Khara)? Did you ever seen neph/aquilon of official faction lolwut around? At last, if he would, there will be consequences inside of faction for that player. Kind of self control.
But Jinx solution - it's just about to punish all Zoner players, even who's used to RP with Zoner caps, not abuse them. Which are absolutely unfair for Zoner players.
ADD:
As for "Persephones"(actually it's a Leviathan class), it's going to be replaced by Nephilim model, because Jinx cant get over this, someone using his fancy toy.
