This is just my opinion, but I feel like the Ultimax and Gravedigger (especially the Gravedigger, given its power) should receive the ragdoll effect that you gave the Bling in the previous update, although maybe not to the extent of the Bling (just enough to knock them to the ground, not enough to launch back 20 feet). I always find it wrong when an almost perfect shotgun blast causes a regular gang member to just stumble rather than knocking them on their ass. Maybe in order to further the gap the Bling could have its ragdoll power increased exponentially. For a while now I've been an advocate for the Bling being the base for a recreation of the Orbital Launcher from Gentlemen of the Row, so maybe this could lead to such a thing?
as for that new weapon, the invisible riot shield, I feel like it's too weak to be a successor to the Pimp Slap; it's about the same as the baseball bat or Penetrator in terms of ragdoll power. Is it possible to increase the launching ability of it to be similar to how the Penetrator works in one of the Whored Mode rounds where it can send people flying into the air? I would say the Penetrator is a better choice for a Pimp Slap successor, but given how easily obtainable it is by player and NPC alike, that idea goes out the window.
