here is a reply from my personal view and experience.
I have a hard time making contact with people, my family describes me as antisocial while i myself think i'm a nice and caring guy when you treat me right.
so my problem is, while i would love doing higher mythics, i just cant seem to find people to do it with, I dont pretend to be a great player but when i compare myself with others i often think "my god how can people be so bad and not seem to be aware of it".
Also, when i do find people who are "my skill level" i mostly never see them again due to cross realm thingy w/e while in vanilla i knew a lot of people just by name on both horde and alliance, just by constantly running in to them in the world and some knew me, it wasnt uncommon to see opposite faction players do /hello or /salute to me and vice versa.
So there you have it, I'm not good at making AND keeping contact with other people, i'm not good at smalltalk.
thanks IF you're reading my little rant
although mostly i just get ignored, or feels like it anyway
