I agree about being able to sell rerolls and leg specific rerolls earned with chests,in a way i understand that they want to keep these exclusive for chests,but in another it will be good to at least sell half of them :
If you have 2 rerolls = you can sell 1
If you have 4 rerolls = you can sell 2
If you have 6 rerolls = you can sell 3

Gold PvP Chest (5% Chance)
Will be great too,so others players have a little chance to have them,even if i also understand if they want to keep them only for top ladder players.
