How many defenses do you upgrade at once?

[Janniboy0312]

Depends in my case. Currently I'm upgrading a Tesla and two WTs though - normally I don't want to have more than two defenses upgrading at the same time, but when the WTs are done... my splash defenses will be maxed so I can focus on point defenses (of which I won't upgrade more than two at a time I think).

[NoobClasher]

Usually use all builders for upgrading defense until they're maxed. I try not to upgrade the same kind of defense at the same time though. Don't want all mortars or all air defense upgrading at once or else the base will be too vulnerable xD.

3 defence at a time,currently 2 AD's and 1 cannon.4th builder open for lego walls.

hmm...

builder 1 : x-bow
builder 2 : def
builder 3 : def
builder 4 : exli upgrade
builder 5 : walls / heros

I only have one x-bow (level 2) left to max. When I'm done with that x-bow. I will probably use that builder to work on my level 1 Tesla full time lol (other three is level 6.)

Usually 2-3. I was having 2 on heroes now with update since king is kinda lame I'm doing 1 on a hero, 2-3 on a defense occassionally I pull on for something else and last open for walls. Usually I do 1-2 core defenses like wiz, mortar, air, or xbow and last on a point defense. Running out of the high priority towers now except for air so soon it will be all point which dont hurt too much having down

3-4 builders on defense and 2 -1 on elixir upgrades or AQ.
Currently :
x-bow , WT , tesla,
2 * DE drill

[aseempahwa]

1st builder- mortars and cannons
2nd builder- wiz towers and archer towers
3rd builder- air defence and tesla
4th builder- barrack, army camp, storages

I try to keep on builder available.

why? This is such a waist.

[PTpirahna]

Last week I had all my air defenses upgrading. The amount of TH9s coming in was insane, but my Lv 3 drill still more than offset the DE losses.

I am upgrading the most expensive, so it depends on the gold, but usually 3.
