Everyone attacks to defend something.
If you dont know the difference between defensive and offensive after I explained it to you, then I cant help you.
And I rarely see a game where you can do "not attacking" and still win.
Anyone who attacks when opportunity rises gains benefits, where the one who is defensive usually ends up missing opportunities.
Even your own behavior on this site is far from what I defined as defensive, but I guess you cant deal with the fact that you are not defensive, just want for others to think you are.
Again,
Defensive = just stopping/avoiding/enduring attacks
Offensive = stopping attacks but also destroy the enemy completely
You can see by simple deduction which brings more win to you and more damage to enemies.
Long live Imperialism!
