Shouting, Putting up PF, joining PF, isn't networking. It's a billboard that gives nothing but some visibility. The question is what do you do with that visibility tool. Networking is about person to person communication and connection. The question isn't how many shouts you make or PF you join. It's what do you do to cultivate a relationship with those you meet. If you have a terrible PF group but one person you notice that is kinda decent, you need to make inroads with that individual. Not just disband and say "another 3 hours wasted". You make a connection with that individual. Team up. See if he has any friends in the same boat he can vouche for. Start up the next PF with him. In the words of bat man:
Gordon: "but you're just 1 man."
Batman: "Now we're two"
If no one helps you then help yourself. This isn't some circle of nobility you must be born into to participate and no one is forcibly holding you out of it. Endgame is a SOCIAL endeavor. You must needs create individual relationships with like minded individuals. Shouts, pf, ls, fc are but tools to help identify people. It is still up to you to make connections. The idea that endgamers are somehow restricting access is, bluntly, wrong. That's is scapegoating the blame for personal failure onto a system of oppression that is imagined. What many do not understand is that their lack of success is a direct reflection of their ability to socially connect. And that is a hard pill to swallow.
PF and df are last resort options that require zero social bonds but still give you a CHANCE to win. There was no pf for months and people still raided. PF is a great tool, but its convenience has led some to become completely reliant on it. This obsessive reliance on PF might be doing more harm than good to this game. Their proper use is as a wide fishing net to catch people and then you decide to keep them or throw then back.
