I want to make something clear that I somewhat alluded to in my previous comment: I don't care where another player's skill level is in something as long as their skill level is accompanied with 2 things: 1: Be upfront about where you are. If you're a casual player that hasn't cleared anything EX or savage and you're making or joining a PF, just accurately portray where you are in that, and 2: Be TRYING to improve. Be open to advice.

If you misrepresent where your skill level or prog point are, you're just going to anger those you're with. If you aren't TRYING to improve, then you're just wasting everyone else's time. If someone offers advice, even if they're rude about it, listen to them. Turning your ears off means you think you're above their advice, and I can assure you, you're not. Even the top ranking player of every job has something they don't know or somewhere that they can improve. Refusing to take someone's advice, regardless of who that person is or how they present it, is nothing but foolishness. Now... that doesn't mean that their advice is necessarily correct... Discern whether their advice is valid or not AFTER hearing it. If it's not, then write it off afterwards.

While I am certainly nowhere near the top of players, and won't try to act like I am, I know that my skill level is substantially higher than the average. Despite that, I'm regularly in a situation where someone who's not even a high end raider teaches me something I didn't know. I welcome those moments, because it helps me improve. Now.... occasionally I get things that are just incorrect... like another DNC complaining that I insist on being their dance partner despite both of us being DNC in a dungeon... Can't tell you how many times I've gotten the "Dance partner doesn't stack!!!"
