Is there any need to upgrade walls beyond lvl 7?
As you can see from my signature, I will likely have 75-80% lvl 7 walls when I reach TH8. The cost to upgrade all walls from lvl 6 to lvl 7 is 37.5m gold. The cost to upgrade all walls from lvl 7 to 8 will be 112.5m gold, which is a lot!
I just looked up the number of wall breakers (WB) required to break through walls and well, lvl 7, 8, 9 walls all can be broken by 2 lvl 6 WBs. So if all your defences are upgraded and elixir upgrades are mostly done, is there any reason to wait for walls beyond lvl 7?
I am not saying that there is no difference between walls that have 2500 HP and those that have 4000 HP, but the costs associated and hence the time and effort required doesn't seem worth waiting. My thinking is that it would be best to move on once you have the lab upgrades you want and the defences upgraded. I won't hae to make this decision until about 3 months, but I just wanted to know what people think about this issue. Obviously, once the gold is free, walls will be upgraded.
walls make a huge difference!
Well first of all, there's the intimidation that comes with the walls... and there's the extra hitpoints to slow the enemy down... and finally, it actually provides us with a way to dump gold/elixir. Loots not yours until you spend it :D
