YES, income for WGT is IMO a good thing as it helps keeps the game alive.
As it is, roughly 2,000 CCs out of the stated 40,000ish CCs participate. I'd be in favor of any changes that increase the number of CCs participating. Such as expanding the prizes, having "tiered" competitions based on CC sizes, tying the Clash to the CC Bank somehow (x credits of the 37cr to buy a CC pass goes to the CC Bank), etc...
