Is he really that broken? Probably don't feel it because I always nuke the s*** out of him.
He tanked Abyssal Altina and a cavalry lance without support and killed both. Abyssal Altina has a special ready and doubles him, the lance still has Abyssal stats.
Ehh i suppose if you're using him I can see it, I've never had a real problem facing him personally but thats probably because I know he's a beefcake like edelgard on a physical match so I choose my encounters with him and he's dead.
