It would be very good to have options for boosting. I would like to boost barracks and spell factory, but for barracks two hours is many times too long to spend with game. If there is example 1 hour for 6 gems, i think i would use boost much often. Optin could be example 1h/6gems, 2h/10gems, 3H/14 etc.
Also spell factory doesnt help much, if you can boost it for two hours and ne spell normally takes 45, min.. I think there boost should be somenthing like 8X.
