hi everyone.
was wondering if you guys could give me an opinion on how to spend my SC.

i'm playing for a few months now and i finally got to my first 100 SC. I purchased all the box expansions and the 2nd barrack, for a total of 65 SC spent. I need to get to 100 for the deluxe stamp card.

Should i buy the 3rd barrack for another 30 SC or spend them all in premium summons?

i know this week there is the drop chance increase but i can't clear harder maps yet so i think it would be kind o f a waste to spend them all on refill to do dailies...
