Upgrade times are plain out ridiculous! 10 days for just one tesla going up to level 10!!!!! Thats why supercell should introduce builder upgrades, a builder to level 2 would take off 12 hours of an upgrade and the higher the builder gets, the less time it takes for you to upgrade your base. upgrading a builder would not disable that particular one it would just take another builder to fix him up. Just an idea i thought of, let me know what you think!
