I do not understand why some people are saying that huge abilities loss is temporary? Its obvious that they list all the abilities which we will have, around ~12 to bind them to A - jump. X, Y, B + variants LT, RT, LR, RB. 4x3 = 12. There may be a little more (e.g .3-4 passives without activation), but not much. So prepare yourself to have not 25-30, but ~15 abilities. I bet all other classes will get the same pruning.
