The way we rule it, "forced movement" is only push or pull, not the target using their own mode of movement (for purposes of whether you get an OA). So you can't use thorn whip to get an OA, but you can with DW.The question was whether the forced movement in this case (2024) triggered OA? The OP says it does, but I thought forced movement never triggered OA.
We've never had the forced movement in 2014 trigger OA, as that would contitute obviously dangerous movement.
