That's a workaround, not a solution.
Some of us don't have that much time, for example, and wish to focus our time one something else thatn a simple grind. We have the cash to spend to help us skip that bit in game and just do what is fun instead.
But now, by the looks of it, in 7 days my account will turn F2P and I will not play it with those restrictions when I am really supposed to be paying and playing without any restrictions.
It started as a problem not being able to buy Cartel Coins, but now it looks like we can't even subscribe to the game anymore, and that's a REAL serious deal. I can live without Cartel Coins, but I will not play the F2P version of the game.
I canceled my sub with my CC to test if deleting its info would work. Ofc it didnt, and i couldnt attach my card to it again, so i was without a sub to the game. But connecting my paypal worked for some off reason, so i got my sub back. Not sure if it works for you, but worth a try.
