Iron Sand Gathering nerf please

This Iron jutsu, which is 3 tiles wide, always takes a monstrous chunk of HP. I'm talking 50-75% HP across most clans, squishy or not (except kaguya of course). This, coupled with a 2-second stun that requires no real aim, is extreme. Since when was Cluster not Iron's strongest jutsu?

Yes, I realize the jutsu is rather slow and requires handseals, but if you're stunned or heavily slowed due to iron rain or iron world, both of which require no real aim... well, you get the picture.

nerd dmg a bit, but also decrease handseals cuz even with 30 it isnt near instant, and heck I've even heard that at 45 hsl it still isnt instant.
