This has already been happening to some effect on PS4. We have fewer high end guilds and a higher percentage of folks on low to middling guilds.
As was stated before, it has been the time committment and not the gold that has been the problem. Our bigger problem on gold has been the exploder Nerf. The game is slower so gold farming goes much slower (we didn’t have nearly as many firebomb teams as the other platforms).
In response, many of our guilds have significantly lowered or dropped trophy requirements. Those that have not adapted quickly enough are falling apart and many guilds are struggling even if they have dropped trophies.
There are many folks that have already quit or dialed back their activity because it was becoming too much.
Adapt and survive or don’t is pretty much the state of things on PS4.
