This composition came to rise during Seasons 1 and 2, and remains extremely popular. It depends heavily on the Mage's " Combo" (a followed by a and ), and the Shaman's burst ability. The name is based on the joke that the Shaman must only hit 4 buttons -- 2,3,4, and 5-- to kill an opposing player. The corresponding abilities are , a , a instant , and a . This composition's weakness largely lies in the lack of crowd control abilities (only the Mage has a silence and a spammable crowd control) and lasting power, primarily due to a Mage's more limited mana pool and inability to drain or regenerate mana as quickly.
