Hey,
To open up alternative content, I think Shadow Lairs should be permanently unlocked at some point, just like Operation Crimson Hammer.
They are challenging and quite fun and it's a shame that its payout is heavily countered by Shadow Keys cost.
I think Shadow Lairs should either be permanently unlocked once you clear all four of them or if you provide 3 shadow keys to permanently unlock a single Shadow Lair.
At least with 3 shadow keys, there is some form of return of investment.
Also I think there should be craftable weapons that use Shadow Lair materials that would be effective against their enemies. Their armors could really use buffs to match endgame armors too.
Thanks and bye
