I too enjoy doing the 4-man dungeons. It's fun just running through with 3 others to me compared to the hectic 8 and 24-man trials and raids. Plus, it's nice seeing your character's progress noticing the change in damage, learning to use your abilities and getting used to the trait changes. For me, it's way to really practice my job and I appreciate that.

Glamour collecting is also fun to me. It takes me back to the days of the original PSO searching for rares hoping to get that drop from an enemy.

Treasure Maps Dungeons are actually pretty fun. It's one of the few things I don't mind the RNG with. Getting a door that seems like it's not going to open only to open at the last minute is so hype.

I honestly just like sightseeing as well. FFXIV has some beautiful areas like the first time you see the skyline of Amaurot. Or that hidden waterfall cave in the Hinterlands. Or witnessing the sunset in Tailfeather. I just wish SE did more with the world that just having it be a place to do fates in.

With that said, I do enjoy doing the sidequests this time around in Shadowbringers beacuse they provide a bit of world building and some actually have some interesting short stories. There's one in Wright that involves a town ghost story explaining how a previous resident jumped off a bridge after her lover died and that her ghost still haunts it. After you investigate you find out the story was true with another unexpected twist. There's a few quests in the Amuro village that are cute too.
