I'm afraid I am in agreement. The level of difficulty is not an issue really, drop rates could be better (you only have to go on the test server and get all the boosters to see how bad they are in reality). Sadly it is the sameness that has led to the game becoming boring. The same old escort missions etc. Once I was clocking around 8 hours per day on PG and now i find that there just isn't the incentive any more. My PS3 (which was languishing and had probably thought itself redundant) loves me again.
This said, I won't stop playing PG BUT I will certainly be spending less time in game (and consequently buying less gold). Another paying customer voting with his feet.
On the plus side, a big thanks to the devs for giving me my life back. (and PS3 says thanks too).
