that's n why you need to learn how to manage resources, if u see that a box cost arround 1m ap (if u buy the 150k ap box) then u wont reroll the 3m and 9m rerolls, because is not worth it, i never reroll those, i started farming with almost 100m ap (95m aprox) and i have 30m left (doing siege everytime and altars in the morning, hm 3-4 times per week) and now I have 4 pieces and 1 weapon so i dont think is that hard to get the new gear.
