Help me here in case Im not seeing something. If I wanted a champ with battle leader I'd run Corgi Ranger. If I wanted a good charging champ id run corgi knight. Even tho it doesnt have heavy charger, it does have more base defense and is a lot cheaper. Both options have better synergy with equips (like elite blade) and are not 2x2. All that being said, I love Fiorn and would love a reason to play him more.
