As a solo player in the early wow era, lfg was a massive pain in my backside. I literally couldn't progress without completing certain dungeons, and I couldn't complete those dungeons unless I grouped up. So I was painfully and perpetually stuck in a never ending loop of LFG.

It's the reason I left.

If you don't have a group to play with, or preferred to play solo, utilizing pick up groups when necessary, the game became an unplayable mess halfway through the level progressions.

They've "fixed" most of this now, but I have a hard time caring about the game now. I went back to it for a short while a few years ago, and while it's easier to nab a group for progression, the onslaught of go-fer quests numbed my brain to any lore that was being spouted by the quest givers, and it became a grind fest.

No sorry, just action.
