It may have some of those extreme feature, but it is just like Pokemon in that you can play and enjoy the game as a normal gamer/casual and have a blast. I reset my account about 20 times to get some good characters and ended up with Roy and Peri, and through additional casual play I've also gotten the following 5*: 2 Camilla, another Roy, Takumi, and Cordelia.
Also got some nice 4* like Raven and Oboro which I might move up to 5* down the road if I don't draw some more 5*s. I already have over 20k feathers through all of the extra promos and achievement awards. Will save them for a rainy day.
Only character I really want that I do not have are Ephraim and Hector.
