You didn’t read the last paragraph clearly.
And early on you were very much bleating on about new player corps and access to toys, and all of the post is relevant to that - being decced because you have war eligible members flying where PIRAT play, or you have structures easily found and in their face. Don’t do those things.
You can’t get better than complete war immunity and it’s easy to do. Then you don’t even need to worry at all about wars for anyone in the corp.
It’s as simple as this, and even if wars were only 1 ISK, your members would still never have to worry about them:
Making wars more expensive isn’t the answer. Just sort your corp structure out so your members are immune.
