Like:
Overall quality from design and technical points of view. No system/feature is clearly bad or buggy and the game runs smooth.
Being able to do almost everything on one char with no hassle.
Dislike:
End game.
Far too easy leveling, especially on DoH/DoL.
Dull gear design (looks & stats).
Yeah, I have lots of history with Korean MMO's and I feel like the game punishes me for trying to put in some effort.
More details about my dislikes:
End game:
I feel that the game stops being an MMO and turns into a coop-RPG with a huge lobby when you hit lvl60. Everything happens in dungeons. I like MMO's because I can play with a massive amount of people in a large world, not necessarily even grouped up. Spending most of my time with 3-7 other players in a small instanced area separated from the actual game world isn't really scratching that itch.
Timers & lockouts & whatnot. When I choose to play, I usually want to get things done. Weekly caps, timed nodes etc stop me from doing that, so I end up not playing at all.
Too effective catch ups. Catch ups are ok and somewhat desirable, but IMHO they shouldn't make older stuff obsolete so fast. As a DoL example I was focusing on red scrip gearing my botanist for a couple of months, then the patch hit and my neglected miners ilvl zoomed past my botanists in a matter of hours. Similar stuff happens with battle classes too. So I won't be grinding my tiny lala ass off in the future. No point.
Button bloat & unfun rotations + disco fights designed to eff up those rotations. I've leveled a bunch of jobs to 60 now and the rule of thumb seems to be that lvl50 gameplay is more fun for me. I think this is a purely subjective matter, but wasn't this a poll of opinions anyway?
I had a summer break from the game for a month or so and came back. So far I've done only one lvl60 dung and that was because FC mates asked me to. I've been much happier doing the lower lvl stuff.
Far too easy leveling:
I get a sense of accomplishment when I first put in effort and then reach some goal. For example grinding levels. But I don't need to put in any effort to get the levels in FFXIV so it doesn't feel like an accomplishment. I leveled my DoL classes without doing a single leve and even then it was stupid easy & fast with the daily GC turn-ins. Can't say I did the same with DoH, I did a few leves to see how they worked. I was happy to see that there was no beast tribe option for 50+ levels but Moogles "fixed" that issue. Yeah, I'm a bit weird. I don't feel like congratulating someone when they reach the lvl cap, more like asking "what's your excuse?" if they don't have it capped.
Dull gear design:
First of all, the stats and the effects. Or actually the lack of them. There's no variance in gear and no set effects. I'd prefer to have at least some options when gearing to fine-tune my job stats to my preferred playstyle. Now it's just "get these gear pieces" and that's it.
And then the looks. In my eyes most of the gear looks dull, cheap and/or just plain bad. My first reaction to lore gear was "Really? This is a joke, right? Where are the real screenshots?". I actually went from miqote to lala because I couldn't make my char look good enough and decided to look silly instead. The glamour system simply lacks glamour. Even if Korean game chars often look like prostitutes, they have some awesome bling bling too. Here the "sexy" toons look like cheap prostitutes.
