Im tired of seeing feats that are clearly not made for division 1 unless you want to use mulitple squads to get them but then you sacrifice losing the round.
I sacrifice for mine - take out 4/5 then time out & restart against a single enemy with whatever is needed. The truth is that I'm not a top player consistently shooting for Kyber. When I play my heart out, I get consistently get close, but not quite there. When I make almost no effort at all, I still get Aurodium, so my final rewards don't really change.
That means that the sacrifice is already minimal, but the truth is that in the vast majority of fights it doesn't cost me the battle anyway. Either the opponent wins by way more than 15 points, or I win despite the sacrifice (which is actually more common). Not very many battles come down to 15 points or less, so if you want the title, my advice is just go for it. Take the sacrifice & then move on & hope for the best.
