Damage required for end-game bosses

Hello fellow Wind Archers
I'm currently playing a wind archer, and I think I got to the point I can attempt end-game bosses.

I currently hit around 20-23m on hmag and got to 25% hp remaining (died out on the 5 minute mark), seems like it's enough damage, but it looks like extremely good control is required.

What do you guys consider a reasonable damage to face end-game bosses?

TY
