Ok OP, I know you'll never answer to this thread because either you are a troll or simply feel awkward to answer to this topic because of people bashing you, but:
What's the trouble of getting another party member and do these missions together to reach your goals?
If you didn't know back then that this game promotes:
COOPERATION
FULFILLMENT
FFFFFFFFFUCK

then I'm glad you've discovered this now. There has been people progressing to 50 alone, but in this game you'll NEVER have fun as more as how cooperative people have. Try it out, man!
