Hmm? If anything I'd run Megahorn over Pin Missile, 'cause there's no difference in damage overall, not Bullet Seed. And as I said, I agree it is really situational, but it could have its uses if one's so worried over the loss of Skill Link, so its use could be justified. You're underselling the value of immediate and realiable (dat accuracy tho ) damage output. But then, again, it's really circunstancial and Pin Missile, imo, should be the preferred move if you're not worried about having to wonder how many times it'll hit in case you're unfortunate enough to get your Hera burned.
