Actually, nowadays it’s very soloable: you can experience all of the story by yourself thanks to the Trust system. I only recently tried it, and control scheme wasn’t as bad as I expected (but you do need some patience). From what I gather you don’t really need to learn about macros and gear swapping mid fight in order to clear story content.

free trial players can be friend-requested and party-invited from non-trial players :)

I haven’t played Dawntrail yet, but I have to admit that I felt something was troubling the game even in earlier expansions: as I finished both ShB and EW I couldn’t help but be left with a state of “oh, tome grinding… again… in the same exact way as all the other expansions”. No one seemed to care, however, so I thought it was my problem. And it’s a big shame, because I expected differently from Dawntrail: from what I heard, it feels more like the character going on a vacation than anything, with really just the same gameplay loop.

Another thing I was expecting from Dawntrail, apart from big gameplay changes, is to redefine the story more significantly: FFXIV up to Endwalker was a great story, but sometimes I couldn’t help it but feel like I didn’t want to be so central to everything: it’s great when MMOs make you feel like “a hero from the sidelines” because there’s less immersion breaking (and FFXI did this succesfully, if I recall). I think writers really dug themselves in too deep of a hole:

From what I hear - reason I haven’t played it yet - is that Dawntrail is fram from such expectations. I agree that once you try FFXIV’s legacy controls you can’t go back. Same thing goes for gamepad optimization.
