Ofc a world without funds would be the best thing ever! But why limitating the caps? Just uncap it! With only 300cp & 2 days cap you cant save stuff for pvp. But therefor, you need to raise the cp income from 10/hour, maybe double it (because every "good" player is only pushing cp till mid) or let the supply remain but make clicking cost 0 or 1 fund so everyone can "click"(which is the most expensive stuff except buying RT which isnt hopefully enabled).
For cost compensation, maybe do an entry fee to participate on the wcs =) But that are all ideas which are well known tbh.
