usually u want to craft all the purple items before buying the two bundle so u find in the pack only legendary and u finish the event with only 70 dollar/euro, u need 9600 blue material too but is managable if u dont use them for 6 month waiting for a prestige or a heirloom u want, and if u want an heirloom that is alredy out or u dont have 9600 at the event u interested in u can pay what u dont have or wait for an anniversary event that usually give 150 heirloom shard and buy old heirloom, so much easier than buying hundreds of pack to find an heirloom
