I must be in the minority but I love these exploits, to me it's all part of the art of twinking.
The angry benches are definitely an exploit and a hilariously great one, I mean it's funny watching them chase unsuspecting levelers who try to fight them. The genuine WTF WAS THAT comments afterwards, then followed with the irony of some pissed off pvper with 2k+ health and with no sticks of their own ranting about them breaking the game. Always makes me smile
