What should I be upgrading? (TH8 - Level 69 - Active)

So I'm a decently skilled player, been townhall 8 for a while now and I'm stuck on what I should be upgrading, if you want to see my base, look up the clan "False Flags" with 12k trophies and look at "Tyrone"'s base. I just got all my cannons to level 9 and I want to start upgrading things that would help me win some more defenses. I am working on my walls, they're not all level 6 yet, but I only have 20 left to upgrade. All archer towers are level 8, my clan castle is level 4, my barracks are all level 9 or 10, and my air defense and mortars are both level 5. Right now I have little to no loot, so I need to start getting more, but for what? Leave some questions on my base or something I should be upgrading for my level or th. Thanks!

My first suggestion on your base is to switch to a farming base. You are a premmie th8 and need to protect your loot so trophies don't matter. As for upgrading, I would say your mortars. Then do wizard towers. Max both of those ASAP. I would then move to cannons. Get those to lvl 10. Then do your archer towers to lvl 10. Then get your teslas to at least lvl 4. Then upgrade all of your walls to lvl 7/8. While that is happening get the king to at least lvl 5. Then you will be ready for th 9 :)

1) Walls
2) Wizard Towers
3) Mortars

I agree with switching to farming base. I always upgrade and max splash first, then cannons, then archers, then tesla. Troops are always the ones I use most
