Out of curiosity, what are those things? Most people I've talked with really like the game and I love it, even though I, for most part, hated the previous PS games.
Of course the game isn't without it's flaws, but I wonder what are the biggest one for you.
Two of the biggest draws of PSO to me were the oppressive feeling to the game world and the sense of weight that went with everything your character did. Both of those things have been abandoned in pso2 and it really hampers my personal enjoyment of the game. I don't like flipping around swinging giant weapons and staying airborne for 10ish seconds uninterupted.
I also have an intense hatred for the free to play system they came up with and wish they would have just stuck with a monthly subscription for a full, complete product at launch.
I dislike that in order to trade items with your friends you need to pay money, its a basic feature that has existed in these kinds of games for a long time and a feature they have already adopted in previous installments of this very series. On top of that every rare item is Bind on Equip and while this is ok in a full blown MMO it is not what I want from a pso game.
I don't like the way the missions system works, and the levels themselves. I would of vastly preferred the way it was handled in pso.
I also can't say im overly fond of the dodging mechanic and the way they implemented it. The game ends up feeling like a poor mans devil may cry or bayonetta and that's not the kind of thing I want out of a pso game.
These are some of the issues that come directly to mind, and while I am glad that people are playing the game and enjoying themselves it simply isn't the sequel I personally want for one of my all time favorite game series.
