Trade Up Armory Data

Allow players to trade up 10 or so armory data for 1 of the next tier.
10 green for 1 purple.
10 purple for 1 gold.
Sure players could farm easy missions to get armory data, but that's still 100 greens for 1 gold or even more depending on what the trade up value was set to. This would allow players to obtain Relic weapons to then take into higher difficulties.
