"Gaining knowledge" doesn't require work. It comes over time.
You can't start in PG and power level your 'knowledge'. There is a large number of players who lack it mainly because, as Khay said, they do not read things. They don't read, they skim. (If even that..)
PG isn't a game that requires skill, I think it would be more 'skills'. One of these skills being reading, another would be thinking ahead/planning.
The real kicker for me is that people seem to have overlooked this sentence by our man Marique:
"I really like the game but after more then a year into it with the only real motivator being gear and only gear and then some more gear the game start to feel kinda boring to me."
I was using 40-50 gear levelling skills to 70, it wasn't the best no, but it got the job done. You're a year into PG, you're at level 50, and you're talking gear? I feel like this is on par with a kid jumping off a bed with an empty pillow case then telling me about their amazing sky-diving adventure. Long way to go, buddy.
