Multiple Builders on one upgrade?
You know, up until Town Hall 7 the upgrade times are fine. I don't have a problem with waiting 3-4 days for an upgrade to finish. But when you have to wait 10 days for something, you even forget that you put that thing on upgrade by the time it is done. Considering the long troop upgrade times on the lab and the upgrade time for the defenses or buildings, the process of upgrading from TH8 to TH9 alone probably takes more time than your whole playtime in clash since you started. Sure the lab times shouldn't be reduced because it's probably a very important economic factor for the developers, but if you can assign multiple builders to work on 1 update, you can speed up the process a bit. You can prioritize a certain building that you want to upgrade quicker than some others. For example, when you first get to a new TH level, the first thing we do is upgrade the Lab and Clan Castle (at least that's what i do). Why not assign 3 builders to the lab and 2 builders to the clan castle to get these important updates finished quickly so you can start with all the other upgrades later on. I am sorry if this idea has been rejected before. I just joined the community early this year.
