I recently upgraded to townhall level 7 and I am currently building the dark elixer storage. I just got the 450 gems from sweet victory III which brings my gem count to 660. I already have my 4th builder hut. My question is, should I use 600 gems for the 10k DE for barbarian king or not? If I don't use them, my gems are just sitting there gathering dust. Please share your opinions on why or why not. Thanks in advance.
