PVP returns to level 1 at the end of each season and everyone returns to the same starting line. This will give new players a chance to make a run for the championship. Attract more new people to enter. If early players have reached level 50, new players are afraid to spend a lot of money on PVP because they can't keep up with the level, and resetting the level every season can ease that concern. This will make each season a competitive one.
