You can hange his A skill for Atk/Res bond so make him tank more, this also has synergy with his weapon. As Fury and Wary Fighter have absolutely no synergy what so ever, only if you have a healer on your team then that Fury/Wary Fighter is not that bad of an option.
I’d keep Wary Fighter as it’s just too good, also his Def and Res are quite high, so I wouldn’t see the need to change his B skill.
If you’re planning to use him on a Armor team then you can keep Armor March, if not then you can go for a drive skill or something else. It’s pretty much flexible.
