Ability points

Why is it that EA at present, as they do in months to come. Restrict the # of ability points to be distributed. Currently its at 18. A team in this game is comprised of 20 players. So. Trying to spread these points out. You are left with 2 players without ability points activated. If a player has been identified with a particular ability. That ability should automatically come into play. If the ideology that EA applies to players in this game, were to be applied to actual players. It would seem somewhat irrational to have that player not utilize a skill. On closing. Why was 20 not the starting amount for Ability points. Rather than 18? I definitely at times have to question the logic with EA, in a game they proclaim to be real to life play.
