Please patch this Exploit: Standing on NewCastle's head to kill him (reviver)

@OldTreeCreeper It's an exploit. Not a hack, and exploit. They're exploiting his ill-maneuverability of the shield to bypass the shield entirely. Ignoring it. It's there for a reason, they need to destroy it or use teamwork to outflank it. Not solo it without either of the above. Had they destroyed the shield this would be another story.
They shouldn't be able to stand on his head like that, it should shove them off swiftly so they don't have the chance to exploit it like that.
AND They should add a head cover so people who do exploit that still have to bust the shield, thus disabling the exploit.

Exploit is in-game issue that causes some people insane advantages over others, like using Rampart's minigun on a Trident to turn invisible (don't know if enemies non-see that though, but my brother couldn't see me. We didn't want to be banned for exploit so I replaced my turret and in using it un-invisibled myself. Story for another time.)

Exploits are not hacks.
Though they are in the same report section as reporting against hackers.
NewCastle needs protection against people standing on his head, otherwise it's an exploit that ruins the game for him.
