He's right on pretty much all levels. They label the game as a "casual fighter", and in comparison to other hardcore fighters like Tekken or Street Fighter, it only goes in to about the depth of a swimming pool, whereas the previously mentioned are more like oceans.
But still, that's pretty damn far.
I suggest you give it a try, like any MMO, before discarding it. It'll take patience, as you start out in the game with literally nothing (we can help you to some extent if you are interested and ask nicely).
