I don't mind Asmongold either, but I think Twitch streamers and many YouTubers are bottom feeders. The fact that he associates with wankers like H3H3, Destiny and Uberdanger says it all for me. If you're looking for advice or actual educated opinions, Asmongold's probably one of the worst guys to get it from.
There's many things to do in endgame, but if what you like about video games is "mastering" the game, you're not going to find that here. I come from a raid background, and raiders clear all the content within days then replay the same raids for 6 months to "get higher numbers". There are many activities you can partake in, like the gold saucer stuff, fishing, gathering/crafting, glamour, mount farming, leveling your other jobs, housing, treasure maps, the triple triad card game, and social activities. I'm really not a fan of the latter, I'd rather stick my dick in a thorny bush than try to socialize with FFXIV regulars, a lot of them are asocial losers and it's high school all over.
I should try fantaing to another race, that sounds fun.
