well, you're trying to use [protective spirit] as a passive defense example. so lets see:
you cast it on a target inorder to prot it, how is it passive? yes you'll give me the "you can also use it actively" so let me counter with: "how do you use it passively than?" and please dont say "spam it on recharge"
AoE defense is the wrong term because not all of the "AoE defenses" are what the game considers as AoE(adjacent, nearby, in the area), just take a look at [aegis] and [defensive anthem] to understand what where I'm going...
and please dont tell me that "all party members" isnt effectively AoE, because it is, just not called that way.
