-atk Alm

I summoned Alm for the first time trying to obtain Flora. He is -atk +def. I know lesser IVs aren’t the worst thing in the world for high tier units like him, but I’m not sure if he’s still worth the effort. With his Falchion refined, with DB, he can kill Ayra but not Brave Ephraim, and with Life and Death it’s the other way around. My +6 summoner support brave build Laslow can kill both, so my Alm’s versatility is limited. Sure Laslow can’t kill Nowi, but a lot of greens can. And I have Marth, Lucina, and “Marth” for other Falchion users. And I have even more sword nukes like brave Celica. Basically what I ask is whether or not I should build this Alm and spend my dew on him. I hate to send him home because Celica and Faye will be sad.
