Hi guys!
I'm getting closer and closer to maxing my th8 base and now i'm confused about what i gonna upgrade next.

Thought about upgrading:
all my AT's to lvl 9 first
All AD's to lvl 6
And then Teslas rush + Walls until max
(i have 4 builders so i'll just upgrade all save up to upgrade all teslas at once, 4th builder will be dealing with those walls while teslas are getting upgrade)

*King is upgrading when i have the enough DE*

what do you say? is this a good order to upgrade my defences ?

*In lab i got the Pekkas lvl 1 that i need to max,Healer lvl 2 need to go to 3, Spells are lvl 4 and i need the Dark troops...

Thought about upgrading my Pekka now and then all my spells and Dark troops

Any commands?

No, do your ADs before you do your ATs.

Me personally I do in order from what's least expensive to the most. In your case, I'd actually try to get those storages up before anything. While doing so I'd also work on getting walls up to par, which would be at least level 7 for now. That keeps gold busy, then keep your elixir busy by researching troops. For my second account I have 4 builders so I usually do:

2 Builders on defenses (One on point defense, 1 on Splash)

1 Elixir upgrades (Alternated with researches)

And the final builder on miscellaneous, which in most cases are heroes/walls/elixir upgrades.
