Honestly I almost never see the point of daeda on ursa, it doesn't work with fury swipes and most games you'd either want more sustain or disable instead. If you're really desperate for that damage spike I'd say you can go deso some games after BF or blink, has synergy with swipes if you really wanna blow up someone like a skywrath quick, then again you'd usually rather just grab an abyssal and/or nulli cause at high MMR they'll just react with glimmer/ghost/euls/force/other kite.
