How to: Disconnect Players with Shitheap ComputersUsing [Buttonwillow's Hand Grenade] from the quest "Remove Their Arms", which is unlocked by speaking to the Quartermaster NPC near Buttonwillow herself, you can keep the quest in your log to gain access to the grenade. Because the new explosion graphics for the hand grenade have been updated to Cataclysm's new graphical system, the grenade does not scale with particle density settings, and will cause a lot of lag for nearby players with bad PCs. The grenade has no GCD so it can be easily spammed. Disconnect people in battlegrounds, do whatever.
