Well, seeing as we're already on the axe appreciation train, I find myself constantly using axe users.
Barst, Cord, Lex, Johalvier, Othin, Halvan, Brighton, Lot, Gonzales, Dorcas, Bartre, Dart, Hawkeye, Garcia, Ross, Dolza, Duessel, Brom, Kieran, Jill, Haar, Largo, Nolan, Vaike, Cherche, Arthur, Charlotte and more.
I have literally taken Darros to endgame in Shadow Dragon. It was absolutely miserable because he was doubled by pretty much everything, and he couldn't hit the broadside of a barn so his contribution was basically nil. One day, I will have used every naturally occurring fighter, warrior, pirate, berserker, axe cav, axe armor, and axe wielding wyvern in the series to end game. Probably. If I don't keep filling up my New Mystery teams by the time Dice and Ymir are available
