There are definitely problems with GAC, but I’m not sure there are any good solutions. Any solution is bound to cause other problems and complaints.
That being said, the original post and followup seem very much like a user error issue.
I’m FTP since 2016 and that’s my read. I remember having only 1-2 GLs and still slowly, steadily advancing after the GAC changes.
I’ll admit that when the LSB bundles for GLs came out it was disheartening to see young accounts instantly jump up, but CG is going to monetize where they can. In the end it made me a better player, learning to be more efficient, out-pointing many opponents where both sides fully cleared.
Everyone is entitled to & allowed to express their feelings and opinions. However, if you can’t find ways to enjoy this universe/game you are purportedly a fan of, you need to do the cost benefit analysis of whether it’s something you want to continue to pursue with eyes wide open to the fact that a company, who is in business to make money, isn’t going to cater to your individual whims.
