Well since i have Sherry the most offensive of all princesess i would not say no to a tank princess that can block 2 units and attack both at the same time with def like an silver-gold HA. Well not to forget her op lightning rod ability with high hp and 20 mr. Something my Sherry isnt realy more suited for then Imelia or any other meat shield.
In the end i would say yes to any tanky unit though i guess since my only tanks are bernard and leanne xD
