Boost x2 x4 x6 you decide!!

[Tyisha]

I think there should be a option to boost your productivity speed by 2x, 4x,or 6x with different variations of gem cost! And or add boost to builders!

Or the option to choose how long the boost lasts. The option to boost the barracks for 1hr, 2hrs, 4hrs etc.

As of right now I refuse to spend gems on the 2hr boosts.
