Silly? You get a free super tiger that you can call in whenever you want. Did you really think there wouldn't be a catch?
If you read my post, I said resources should drop to zero for the duration of the tiger ace's lifespan, then drop to something like 50% for the rest of the game.
Its game over now if you lose it which is a dumb mechanic. nerf the tank if required and get rid of this mechanic.
nice soviet bias btw.
