New players to the game can quickly and easily reach level 70 then without putting in the dozens of hours everyone else has so diligently spent AirRivals spi on their cheap AirRivals characters. For their part, Blizzard has spent recent months working extra hard to ensure that the use of bots does not become a bigger issue. They have banned thousands of gamers for using them. However, this does not stop the wide spread use of bots, it only makes the bots more advanced and slightly harder to detect.
A boot itself is basically just a piece of software that automatically interacts with the game in place of a human player. It speeds things up for a player by making it so you dont actually have to play the game, merely turn a boot on and let your character level up. Eventually theyll be strong enough and have enough AirRivals gold that you do not need to worry about the boring lower levels of the game anymore.
