Could make it a block-able dagger, with a full body block that looks like a shield, high delay and a knockback effect with low (10?) damage. 800 ish delay would make it just a shield bash in essence.
Imagine this on Atk/Def when you're attacking and you have the enemy team doing that obnoxious pop out and RS spam on the corner, being able to block their attacks and knock them back for your team.. or tunnels on garden. I think it would be fun, I'd be an instant convert since I refuse to play the meta (mostly because I'm terrible and my wrists are jacked).
Edit: Lunge works with the idea of a shield charge, knocking people onto their back. It makes sense!
