Level 11 walls should deal damage

I think that level 11 walls should do damage and I know people are going to say that this is way to op but hear me out level 11 walls have an arc of electricity and that should do damage to one attacker that is attacking that wall it should have the same damage as a level 1 or 2 hidden tesla and please comment

The arc of electricity that flows through them is just for looks, and that's still way too OP.

It's not like it's attacking the whole army the radius would be the 1 and it would only attack one troop so if you have like 50 level 5 barbs attacking one wall it's only going to kill 1 or 2 barbs
