Oh no, we get it. Let me break down for you the basic insight you have discovered.
Insight 1) Different people play this game different ways and that is ok.
Got it, that is the novel insight. Some people like to play in permadeath, some people like to play in PvP, some people like to min/max or shoot for epic questing. This isn't news. There is, however, a catch that you need to get.
Insight 2) You are not entitled to join anyone's group. You are welcomed into that group by the other players and if you don't match their playstyle then it's their right to refuse to group with you.
I don't play permadeath style game, but if I did get into a permadeath group I wouldn't suddenly run off, die and expect to be raised because that's not how they play the game. Similarly, if a low con, low dps character that intentionally under-gears for 'challenge' joins a group aiming for fast completion times, high quest-level game play then we're going to do two things:
A) Offer you advice on how to match your build/gear to the expected playstyle of the group.
B) Tell you that while we valued our relationship in the short time we had together, its time for it to end. No really its not you, its us baby. "Player Low-con, low dps, Elf has been removed from party"
Now, if you understand both of these insights, then I can only assume you are posting to the forums to tell us all about how you play the game. That's nice and all and I hope you enjoy the attention while it lasts. Nevertheless, I think people on the forums got confused because you said "Some People don't get it" and then listed an experience you had with a pug. We thought you didn't understand why the players in that group offered you advice. They were offering you advice on how you could match their playstyle if you wanted to group with them. If, however, you quite seriously do not want to match their playstyle then you are by all means welcome to start your own LFMs, but they are not required to group with you.
