Roger that. Just found it. I'm not sure what happened back then anymore either. I once had all the notes but they went poof along with all my attack chain spreadsheets. If I'm going to be honest, based on what happened on beta with BZB and a pylon, and the rework they had to do because of it and other testing, a bad AoE calc makes sense.
Edit: Just want to throw this in... (and, no, this is not in any way directed at Bopper) Claws is my favorite melee attack set. And yet I'm ok with a nerf if it means that the underlying equations gain balance and equity.
This comes from me not being in the "screw you, I got mine" camp of life.
