I wouldn't complain if it was just an ingame item.. or some other pixelated bauble, but they are essentially giving away cash. A $14.99 credit. That's something tangible. That's money in my pocket.
And then to also tell me I am not a valued customer, even though I pay the same subscription as everyone else, and have been here since the beginning, while others have probably been here less than me but just because they powergamed to the end they are some how more valuable. Sorry, but that's just wrong.
I've dealt with the bugs, the issues, the failures and not once did I ever consider quitting. Being told I don't matter, that I am not valued, yeah, I am seriously considering it now.
