Zant Heart container A15 (Legends)?

How the hell are you supposed to get A rank on this one? It's a 3x "kill the right hero" map. Unlike on the Wii version where the last matchup is Ganondorf + Midna (kill Ganondorf), on Legends it's Ganandorf + a fucking regular Bokoblin. How the hell are you supposed to kill Ganondorf without killing the Bokoblin who dies in 2-3 hits???

If you break Ganondorf's weak point gauge once, the AoE instantly kills the Bokoblin. Are you seriously just supposed to kite Ganondorf in circles while chunking him 1 regular attack at a time? If so this might be the worst designed level in history

Edit looks like you have to exploit the terrible AI. Stun the Boko with your boomerang then run to the opposite corner and turn your camera so he's never on-screen. The Boko won't move again until he comes back onto screen
