When a Paladin in World of Warcraft Activates the spell "Divine Protection" where he/she is sealed within an impenetrable bubble-shaped shield of holy magic that prevents the Paladin from being damaged from aggressive spells, curses, melee strikes, and ranged attacks. The bubble lasts for a limited amount of time, but at higher levels, allows the Paladin to stay in the "Bubble" for the amount of time that a Hearthstone
may finish casting, therefore allowing the Paladin to Bubble-Hearth
in other words remain invincible so they can use a Hearthstone to warp out of danger and into saftey. This makes the paladin envied and hated because enemy players cannot be able to finish off the Paladin, nor interrupt the Bubble, since it is an instant cast. A paladin may also Bubble-Heal to make himself invincible and then cast Holy Light, a healing spell that is allowed to be Self-Casted by Paladins, as well as casted upon a friendly target. And since Holy Light requires a casting time, the bubble prevents any spell interruption, or further damage to the Paladin during the time it is active. Some people say a critical hit of 10,000 damage points can instantly bring down the bubble, as well as inflicting full damage to the Paladin. The bubble gives the Paladin a huge advantage. Sadly most Paladins are played by immature, or young players, as well as noobs. Possibly because Paladins get free Mounts, Heal, and bubble, making it E-Z street. Paladin is nicknamed Pally, for short.
