I think it would be cool if you could spend some xp to upgrade a kit you own. For example : Level 1 Warrior : Knockback 1 wooden sword, Potion of Healing 1, +1 melee attack damage. Level 2 Warrior : Knockback 1 wooden sword, Potion of Healing 2, +1 melee attack damage. Kit upgrade : 5000 xp Level 3 Warrior : Knockback 2 wooden sword, Potion of Healing 2, +2 melee attack damage. Kit upgrade : 15000 xp. I think it would be an awesome feature What do you think?
