ikr but I still think this is a good call. Maybe adapt other gamerules to do it but isn't important tho
Dq'ing people via striking them out-of-bounds is pretty novel. Although, it seems a little bit like an entirely different meta from lenshu. I think you stumbled upon a neat sort of gameplay concept but I wouldn't compare it to lenshu.
Almost actually makes me want to make a similar mod fleshing out the meta.
