Work 2 Game is a tough one for me. Their videos seem to waver so much between interesting discussion and blatant click bait that I can't say I'd personally recommend them. Out of all of the FF14 content creators I do watch, their videos have the lowest completion rate. It seems I'm just as likely to watch all the way through as I am to just click away after 2 minutes.

Other than the big names already mentioned, I'll throw in TinyBlueGames. He's still fairly new to 14 (or at least is still progressing through HW atm) but he's an MMO vet who brings a fun, new experience to the game. It's always nice to see someone truly experiencing the game for the first time instead of just watching the seasoned, grizzled veterans.
