unfortunately upgrading armor and weapons in this game is VERY unsatisfying.. most armor and weapons if you max to T4 the next gen is literally just marginally better. In order to make these jumps feel better my friends and I only go to T2 on our gear.. that way when we get to the next set it actually feels rewarding. This game does not really respect your time in regards to material costs to upgrade gear. It's fluff grind disguised as content.
