Arena

Arena draft appearance rates have been adjusted.

Note: Non-Basic Neutral Classic minions represent the baseline for draft appearance rates. Basic/classic neutral minion: .5x Non-basic/classic neutral minion: 1x Most recent set neutral minion: 2x Basic class minion: 2x Basic class spell: 3.5x Non-basic/classic class minion: 2x Non-basic/classic class spell/weapon: 3.5x Most recent set class minion: 4x Most recent set class spell/weapon: 7x

As part of our ongoing efforts to improve Class balance in the Arena, we are making small, periodic appearance rate adjustments to specific Arena cards.
