when u acs attack someone
u will have also the people whe defend it so make a better simulator included this and the lost of everyone

The ACS defenders are just added to the total of the 1 defender.

we shoud add it

Why?

coz we can make many defender to protect the planet

it is going to be a redundant addition. First of you have to understand how acs defend works. It do not work like acs attack as each participants defends with their own WSA specs. ACS defending ships no matter how many players participates everyone's WSA is flattened to the original defenders WSA. SO it acts like a single fleet rather than how it is in ACS Attacks.

So I do not find any utility to adding more than one panel for ACS defend fleet specs.
