Yeah I played it over the weekend and was not impressed. The graphics are good, but that's about where the good stops. The combat is pretty boring, you just click click click to swing your sword or whatever, maybe hold click to charge up your swing, and right click to block. You get a few skills so you can press 1 or 2 to do a special thing.
I'll say the voice acting was kind of cool, impressive to see in an MMO - and the environments were sorta cool. However this honestly felt like I was playing a single player TES game with other single players running around too. The graphics aren't as good as Skyrim, and definitely nowhere near a modded Skyrim so even though the graphics are good for an MMO it still feels like a downgrade.
Most quests I had were "Go here, press this lever, come back", "Kill these things, talk to person", etc etc. I found myself skipping most of the dialogue and the lore parts.
UI is alright for a new MMO, though I'd imagine if they allow mods all that will replaced pretty quickly anyway.
There's no way I could see myself paying the $15 a month for this..
