Full Storage Post-TH upgrades?

Basically the concept of this is to fill up your storages as TH is upgrading to buy the MOST expensive new item.

Example: TH 4-5
Purchased Wizard Tower. Upgraded Wizard tower.

TH 5-6
CC level 3, cannon level 7
Healers (barracks level 8)

TH 6-7
2 Hidden Teslas
Level 9 Barracks

Btw, I don't rush. I made the mistake of going TH4-5 without upgrading my level 2 walls but I corrected it and left TH5 with all gold walls and nothing to upgrade. Same with TH6, I maxed absolutely everything. I plan on doing the same with TH7.

These upgrades were all purchased as soon as the TH finished.

What should I do for TH7-8?

Get your dark drill and 3rd ad!:D

Teslas are a strong defense, especially at higher levels.

Will consider elixir drill. But I need upgrades that will cost about 4 million gold and elixir.

The first things I like to upgrade at each level are the Mortars and the Wizard towers because they do the splash damage and therefore do the most damage to the attacking troops. Besides the wizard towers are the easiest to recognize at the higher levels.

What I did was up my lab, get the DE drill, get the WT, get the AT and storages, upgrade them until the end of the day, and get the AD.

(So many acronyms!)

What I will do when I upgrade is, with all five builders:
1-upgrade lab to lvl 7(2.5 mil elixir)
2-upgrade spell factory to lvl 4(1.6 mil elixir)
3-build archer tower and extra storages/traps/etc that take minimal resources/time - do archer queen with this builder(does it need one??)
4-build air defense(22500 gold)
5-build&upgrade to lvl 7 15 walls(4.8 mil gold) and build 10 other walls and upgrade to lvl 4(162000 gold) then start building wizard tower(1.8 mil gold)

After air defense finishes, farm for the remaining 2 or 3 mil for the walls to lvl 7 and keep that builder open for wall upgrades
After small buildings builder finishes, start building the drill
After that, it's kinda up to you when you wanna farm for the xbow and the tesla towers.

Lab should be done almost immediately as you always want to start your next lvl troops asap. Then it's a matter of preference. I try to at least start building all new structures and get my base layout and upgrade accordingly from there (starting with the new ones, and upping them to my current lvl).

Splash...mortars, and wiz towers are always a top priority for defense and should be done as soon as you can afford so.

As for the drill, yeah it's good to start pumping out that de, but I wouldn't prioritize it over the lab or spell factory honestly. Plus, the benefit is minimal de until you get it to at least lvl 3 imo which costs quite a bit of elix.

For TH7 you'll also want to get the de storage asap so you can start saving for the BK and other dark troops.

I have two dragon barracks and am on my third but contrary to your suggestion I am postponing DE raiding to the very end. I get how a ton of people would want their BK early but I think it is a big mistake to try it without proper defenses. My current plan is to upgrade all defenses starting from wizard towers down (I always do most expensive first) to cannons. Then my troop upgrades especially level 2 dragons, then walls to level 7 and BK. I do not intend to "rush Dark Elixir" as at the moment my troops and defenses are too low and I am currently chilling in Silver 2-1 picking off small 100k raids with simple Giant Healer Goblin.

I just don't see the benefit of going early, can anybody tell me other reasons to consider?
