So a little bit of the backstory. I originally played on PC but never got very far, only in the 20s I believe. However I eventually picked it back up on PS4 (cause I had friends there to play with), and also did so with the DLC.
I got to say, the changes they made from when the last time I did were amazing! The One Tamriel update helps the game so much! This time I wasn't just doing zones in order, I could go and explore any zone no matter my level. So with that, I actually went to the DLC, Orsinium, before I even completed Stonefalls (cause I picked a Nord.)
It was awesome and the zone design was great and a step up from the other zones. But even then, before One Tamriel, you essentially had to beat the main story before you could even see other faction zones. Yet now, it doesn't matter and I can even play with friends no matter what faction they're. It's just really liberating that no other MMO really provides at the moment. Most even more 'open' MMOs still require you to be a certain level before going to higher level areas.
The questing is also really nice. Granted some are simple go here and touch that thing but I found a bunch that actually had decent stories and got me invested, enough to want to find out what happens and even to make me ponder before making a choice.
Also when I originally played I never did any of the later dungeons. Well now I have and they're so much better then the early dungeons! The bosses actually require you to learn mechanics and it becomes more than simply banging your weapon against an enemy with large amount of healths. Hell, with One Tamriel you can even do these dungeons at low levels. Granted one should probably still do the earlier dungeons to further learn how to play.
Another thing is the skill system. While some maybe turned off by only able to have 10 skills and 2 ultimates (5 skills and 1 ultimate per weapon), I think it's nice because it means you have to really think about what skills you want and what ones will work the best for each other. Then you can even specialize skills between two versions which just adds another layer of customization and since many skill trees are not class-specific, it means you have so much choice. I can't wait to make a second character and try to make them play radically different from my first. (Which is a bit boring to others, 2h handed Dragon Knight.)
Still I'm enjoying my time and now that I completed the main story (which again, really good! The later sections when you arrive at

My only real complaint I have is that I wish the combat had more feedback. When you charge up a heavy attack, you do feel it. The controller even rumbles. But I wish for light attacks that there was a bit more... "umph" to it.
Also one last note, at Native 4K and HDR, the game can be quite the looker on the Pro.
