Well, first of all, you did not "buy a product" you donated for the project out of free will. The project in return promised you benefits in-game. Its like charity with recognition. So no complainig there.
Now, in regard to gameplay - I absolutely agree with you. Gameplay is shit. Constant lags, dcs, log in problems. Even if you are able to actually connect and play you dont really manage to do something during prime time, every location looks like a warzone, and you need to rat mobs especially in high quest locations. Sad.
Honestly I dont know how thing are going to go. No info from admininstration team also demoralizes.
