I definitely want to raise some complains like taking out units like Garret and Karel, Garret is your second berserker and is still a usable one too, he can be pretty good if he was made into a good but not as good pre-promote unit, in case you didn't want to use Gonzales and his bad skill, or Geese and some of his other problems. You should remove Bartre if that was the case with Garret then too, since both Lot and Wade should make Bartre irrelevant, especially the fact that people tend to choose the side that doesn't have Bartre anyway.
Karel is also useful in his way, late-units with high stats were always useful in the end game, like Athos, Gotoh, and Nagi, Karel should be one of them too.
Also, Lilina is better with a fire tome actually, since her low skill is fixed by a fire tome and she fixes the low damage of fire tomes with high magic.
