I think it is a bit to much elixir to upgrade the Dark Barracks.
Level 1: 750,000
Level 2: 1,250,000
Level 3: 1,750,000
Level 4: 2,250,000
Level 5: 2,750,000
Level 6: 3,500,000
Now i don't know about you but I would rather spend 1,750,000 elixir on something else like a lab upgrade than get Valkyries.
Please vote to tell me what you think the cost should be.
