It has recently come to my attention that nair sets up for dair perfectly. So much so that it is actually a consistent KO as low as 95%. This could be the answer to Samus' lack of early KO ability. Nair still has lots of priority, speed and stun. This coupled with the lowered knockback means that when you intercept their recovery with it, it knocks them just far enough to follow up and connect with a dair. Try it out. This could be big.
