You don't miss anything because the whole point of the game is being MMO, not to be a game to enjoy and also have fun with friends. However there is no MMO I liked for they only care about being time wasters instead of having meaningful content to have a good time, DQX is the worst MMO I played. It has a generic main story, generic stuff, generic MMO quests and generic gameplay so nothing worthy to play in it. It's only for die-hard fans that couldn't get enough of all the DQ they played over and over again so they wanna spend their time in a DQ MMO.
However for a friend once I checked it had English translation project that translated its launcher and main dialogues enough to play the game, but side content wasn't translated which required real-time translator or something in your own expense. The only other issue it has is finding an ok Japanese VPN and after every time you play you need to switch Japanese VPN after your account is frozen for "suspicious activity" so you bother unlocking it by wrestling with Japanese emails and Japanese website of the game all the time. Because of this my friend gave up playing it especially because "it doesn't worth it for game is not good enough" and I made his DQX experience a meme lolol:
However I'm mostly bothered by how suck it is to be free player and simple side things takes insane amounts to do like to change one piece of armor's color you need to grow flowers for 1 week real-time or pay too much money for simple features. I was like "ain't nobody got time for that!!!!" and dropped playing the game. No decent stuff to wear for my superstar character for being a free user anyway!!!
