Life grip

Life grip aka Leap of Faith is probably one of the most abused skills in the game giving people an extremely large amount of grief.
Added in a very early Warlords of Draenor patch 6.0.1.18125 was introduced an item called a Neural Silencer which blocked people from using life grip on them. Obtained via Blingtron 5000.

Very rarely actually used for good.

Notable appearances are:

• Supa falling victim to Freezy's wrath during Blackwing Descent trash on the way to Maloriak.[[1]]
• One time Atena LoF'd Heaton through the Nightwell during the Elisande encounter and Heaton rage-kicked all the priests out of the raid, resulting in a wipe.
• A strategy during Elerethe Renferal aka Spiderbird was to stand right on the edge of the cliff or webbing and wait for an unsuspecting Heaton to run past, grip or Swapblaster him and he may mistakenly move and fall. Atena and Freezythree were the main culprits with surprise appearances from Dunbaron. Heaton eventually caught on and kept paranoid checking who each of the priests were targeting. He eventually out-smarted the priests and started using neural silencers.
