So I beat Echoes Shadows of Valentia and I feel that for 3/4 of the game, units are scarce. But some of them I think are Great!
Amazing: Dread fighter Tobin, Kamui, and Saber, Sage Kliff, Alm and Celica (duh), and Mathilda.
Great: Bow Knight Leon, and Python, Saint Faye, Gold Knight Grey and Clive, Paladin Conrad
and then the rest are for you because I can't think, I missed out on some units, or I havent used units enough to know. But last one
Absolutely terrible: Jesse (xD)
