Neutral or -Hp +Def L!Ike?

-hp is his best bane and he can work with any boons

without a doubt, keep the hp bane

I'd say wait until -HP +Atk/+Spd but that's just preference, +def is amazing if you're willing to fodder B!Ike and QP 3 from someone

He'd appreciate the defense, and HP is one of his more dumpable stats. Either way its about the same.
