here's the deal
once upon a time, you COULD upgrade walls without a builder and you know what? the economy was horrible. there wasn't ever any loot to find.
then supercell changed it so you had to have a builder to upgrade the walls because it helped the economy. if the reversed the decision, in a week you'll be back asking for it to be back like it was! seriously.
it's fine the way it is.

Actually, a wall only takes a few seconds to upgrade. Saving for all the walls to be able to upgrade each piece takes long.
If you don't have 4-5 builders than you wasted your gems, gemming things that didn't need to be gem'ed. Pretty easy to get to 4 builders. The 5th certainly takes much longer
Comes down to planning. Time your builders to finish at different intervals. Do your upgrades so that one builder is finished in 2 days.. another finished in 3 days.. another finished in 4 days.... or depending on your level I suppose... 5 , 7, 9 days... whatever...
Nope...and no thank you...Upgrade wall with 1 builder is good. You dont think so?? Go TH 8 or above and you will see what I'm talking about
^this x 1000!
A guy in our clan is TH8 now with still only 2 builders. He's always whining that "upgrades take too long now" and "I can't raid" because people will steal his loot before a builder comes free.
I told him (repeatedly) this day would come back when he was TH7 gem-boosting his level1 DE drill to "get my king faster..."
