Everyone to their own opinion dude. You find it funny to spend that long in Flex - I don't. What makes you more right than me?
I don't forget that this is a game, I just don't want to carry random bad players. I invited like 6-7 socials to a full Flex run this night and only had a few boosters. That would never have been the case with randoms, since I owe random players nothing. That doesn't make me a bad person or an elitist whiny asshat though. That just mean, I chose to spend my time helping guildies and if I need to pug, I sure as hell won't carry bads doing less than 100k.
Call me elitist, whiny or w/e all you want, it still doesn't make you more right than me or anyone else. Cause after all this is a game remember and in this game, I'm free to do as I chose, free to play with the people I chose, free to set minimum requirements for pugs as I chose and free to kick bads who can't carry their own weight - all so I can have a faster run.
That's the great thing about Flex, nobody forces you to run with players you don't want to. It's not like LFR where you can't really do much about random players being shit, being abusive or afk.
Tl;dr: Your way of having fun is definitely not my way of having fun.
