I've been really enjoying the game so far, especially the epic cutscenes which are the Main Storyline Quests. But there is a resounding issue that I have with it. I just feel that as an MMORPG, you should be able to go through the story with your friends and not be forced to do things alone.
I get it, Naoki Yoshida wanted to make an MMO that would gently get people new to them more into them and understand them better. He didn't want players to "have" to be in a party to do content. And that's nice. The option to do things by yourself are there. But I also believe we should have the option to do things together. Not just in some parts of the story, but in ALL the parts of the story.
I feel that the defining feature of an MMO game is slightly lost here. Isn't the point of a Massive Multiplayer Online Game is to play... well... multiplayer ? I'm willing to overlook this, since its the first iteration of this game. But future expansion packs should focus more on multiplayer mechanics. Solo should be an option, not a mandatory thing. I hope the devs read this feed back and take it seriously. The game and the story is much better enjoyed with your friends by your side.
