The title pretty much coveres it. What do you think if that kind of chest would be available in raids? A chest with seven floating orbs above it. You can earn keys by doing raid dailies (3 keys available per week) and the loot gets better when you have all three keys. Like you get a loot box for every strike mission you did after opening the chest the last time, you get a loot box for every raid wing you cleared after opening the chest the last time (therefor seven floating orbs above the chest). Maybe it could also be sufficient if you just kill one boss minimum for each wing to get the loot box for that wing. For example: kill Deimos, get the wing 4 loot box when opening the chest. Or you have to clear the full wing to get it. What do you guys think what would be better?
Also, the rare rewards in the chest should be pretty much the same as in the strike mission chest (precursors and so on). But the common rewards should be a bit more valuable considering the difference in difficulty of strikes and raids. Instead of a map currency, the raid chest could award gaets cristals and magnetite shards.
