Why do we still have enmity?

[Jandor]

It's one of those things isn't it, everyone says enmity isn't an issue at all, often leaving out the so long as everyone does their bit to manage it factor.

Well, yeah, so long as everyone is managing everything correctly HP isn't an issue either, neither are enrage timers, or any other mechanic for that matter.

The difficulty in this game comes from harder encounters requiring you to play closer and closer to perfect, enmity is admittedly a rather low hurdle to clear on your way to perfect play, but games do benefit from having some easy hurdles to clear at the start.
