bernard is better then leanne vs mage units because he has more hp and defense don't matter. Other then that , a leanne at max level and skill level , has (when she uses her skill , ofc) the same defense as a maribel at max level before AW , (which is a plat), during maribel's skill usage (when she gains black tier - stats). That's a crapload of defense for a silver unit mate. She is rather strong for a silver , and it's generally accepted that she is a tier above bernard
