Upgrading order
1. Laboratory SHOULD always be the first first first thing you upgrade, because better troops: higher chance of winning a battle
2. Mortar, great at splashing damage on archers and barbarians
3. Wizard tower, great at splashing archers and minions
4. Cannon, giants are present about one battle on 2 and cannons specialize on taking them down
5. Walls, most people think that walls are useless but in my opinion, they're so good defence, even better than the mortar because when most people are up to fight someone with high level walls, they press next before even checking the base design( happens to me quite often). Walls level 8 and 9 are quite scary . During this upgrade, I highly recommend you guys to upgrade your barracks. Did you ever felt like you didn't want to get revenged with 10 dragons?( that's how you feel when you see all barracks level 10)
6. Army camps, more troops = higher chance of winning a battle
7. Clan castle, this is the strongest defence in all the game. 10-30 archers coming out from your clan castle is probably the thing that will slow your army the most. The only problem with this defence is: two attacks in a row ( first wave kill the troops and second wave gets a higher chance of winning) and your clan( if there are only trolls that give goblins and wbreakers).
8. Xbows if you have townhall level 10,
9. Spell factory, can make a big difference when you start a battle with only 1 mortar left to destroy
10. dark elixir drill, more dark elixir => better barbarian king and archer queen => higher chance of victory
11. Archer tower, can kill troops that hav a lot of hp fast( giants, healer, wizard) but are weak against group of barbs, minions and archers.
12. Air defence and hidden tesla, both take a really long time to upgrade, I would recommend divide the job. 2 builder for tesla and 2 builder for air defence. It's upgrading slowly, but you upgrade two stuff at the same time ( this is to avoid getting 4 air defence in construction)
13. Dark barracks, they have low hitpoint, upgrading them makes it harder for your opponent to get 50% and slow their army a little bit.
14. The only thing left are mines and collectors, I think it's useless to upgrade them and you should just skip this step but, if you're an inactive player, this is a good option
15. Townhall, finally
===> I didn't mention the storages because I think they should always be maxed anyways , but if you didn't, upgrade them right after the clan castle.
this is my current upgrade order. Do you guys know how to improve it? Tell me what you think about this .
