While leveling multiple jobs I will say the one thing that annoys me the most about this otherwise awesome feature is that I have to move abilities around each time it occurs, especially if level 30+ and get Randomed into a 20 or under duty/fate.

Since all abilities are Potency based can we just have the level scaling effect just do Stats, Traits and Gear but leave core class/job abilities alone. Even the extra cross class slots I can understand locking out but loosing some abilities that are very rotation or reaction dependent, ie tanking it is frustrating.
