LOL, it was 4 vs 2
You have no idea where Morley, Karasu and Ledberg ranks in combat.
Most of us guessed before the clash that Sabo teamed with someone against an admiral, while Karasu and another teamed on another admiral.
And the Sabo stayed behind to let others escape is not mentioned, it's fan speculated to justify the loss. I wouldn't mind it, but it was NOT MENTIONED YET. If others escaped, they would have appeared in the page that has Dragon and others. but all 4 got a beaten. It's as simple as that. And again, it's 4 vs 2
Making it 2 commanders vs 1 admiral
At the VERY VERY VERY BEST
it would be
Sabo vs an admiral
and
3 commanders vs another admiral
Regardless, two admirals did not jump on Sabo lol
