Wrath doesn't work for me on Nephenee by the time I can give her Luna. Her hp never gets down to the half unless I don't heal her for several turns. She always caps skl and Luna activates highly often dealing the extra damage I need to kill an enemy in one round.
Also I only use two paladins. By giving them Sol and Aether to Ike I'm done, the other units I use have bad occult skills. So this works perfectly for me, surely with other teams it would be different.
