Scale really does matter though.
If a single forged letter had the Zuma straight up destroy Terran without waiting, then yes I'd be pissed too.
However, if the Zuma only destroy you if you try and destroy them, and do lesser punishments for lesser things, than that is balanced imo.
You lost a region? So what, monsters and undead do that all the time to the rest of Dwilight (or used to). You're safer from monsters and undead because of the Zuma, so that is an advantage for Terran.
