As everything else in clash of clans can be boosted I wondered if this idea has been thought of. I would like to formally suggest to allow the option to gem boost builders work as they upgrade various defenses or barracks. I think that it would be a big hit among coc players. I don't have any details as to how many gems per hour left to upgrade. I simply wanted my idea seen or read again, if already mentioned, thanks for taking the time to read this. I hope that it can be something implemented.
Please let me know your thoughts and opinions
