No, it shouldn't have. Snideness doesn't suit you.
First off, to clarify, I'm not one of those "free players." I'm also well aware of the FTP market, and its trends. I'm not suggesting that buying trophies stops giving a noticable benefit. The item markup could be set high enough to ensure that's not the case. Perhaps the COP items for gold only was priced too low?
My point is simply that there is no reason to get excited about getting a lot of gold in this game, and there's very little interesting decisions to make. For instance, if gold is maintenance only, you don't have to decide whom to equip, or if its better to heal a wound or save up for items. I imagine this is especially true for those who don't pay and can't have more than a few purps for their stable. It's an area that should be looked into improving. The suggestion the allow blues and purples to be purchased for heavily inflated prices is a possible way. I'm sure there could be others as well. Perhaps temporary bonuses for spent gold?
Trophies are not the issue. That mechanic is fine. It will need to be kept in balance so they are still valuable, of course. But right now gold is boring, even if it eventually begins to regain some of its value due to spiking maintenance fees.
