Each Arena Season will bring a unique set of Arena Rewards. With the onset of a new season, the previous rewards will be available for a 15% discount, while the predecessor to that set will be available for purchase with honor and battleground tokens. For example, with the start of Season 3, Season 2 armor will be discounted 15% while Season 1 gear will be a battleground reward. However, Season 1 gear is not longer available as battleground reward, since it was replaced by Season 2 gear at the start of Season 4, and consequently replaced by Season 3 gear at the start of Season 5.
