Instead of only having 2 options on upgrading defense, which is wait for it to upgrade or use a ton of gems to finish quickly, why not have a boost option on upgrades as well? That way it doesn't cost an INSANE amount of gems but it will speed up the process. Most people would be more inclined to boost an upgrade than to spend hundreds of gems to finish it off immediately. Resulting in MORE people using gems vs waiting on it to finish in 8 days. 😊 Just an idea that came up in our clan and everyone agreed, they'd actually spend the gems to boost when they normally would have just had to wait the 8 days. (8 days is just an example 😉)
Thanks for reading this! You guys at supercell are doing a great job!!
