Before you ever get to the process of actually upgrading or crafting weapons, you need materials. And they don’t come cheap. Nowadays, Bungie’s Destiny lets you buy materials but in the beginning, you had to memorize farming routes on each planet and set for hours upon end to get what you needed. The Division is worse – the Dark Zone is the only place to acquire High End Division Tech and someone else is likely to get it before you. In a way, Dark Souls and Bloodborne can also be considered since they require Souls and Blood Vials for the leveling process but neither ends up as aggravating as the above.
