Queuing upgrades could be so convenient but you MUST HAVE THE VALID LOOT AT THE TIME otherwise queuing simply just does not respond! Queuing 1 upgrade at a time. I think this should be unlock at th8 and up. When people dont have the time to log on it will be easier for an upgrade that is queued to just simply start. I also think queuing spells aswell but upgrades would be amazing and maybe even a cool down involved.
sorry for those who disagree with a cool down but queuing could just simply be a bonus at times and not so frequent but i do believe it should be an UNLOCK at around th8 or 9 and then on.
