So after enjoying Wildstar for regrettably the final time, it dawned on me that a system they use could be done in this game: Interrupt Armor.

For those who never played Wildstar, interrupt armor is basically a stacked buff on bosses and elite mobs that prevents it from being crowd controlled, BUT using a crowd control ability like a stun removes one application of that interrupt armor, and removing all of it would mean that it could be prone to stuns and other forms of crowd control. Some fights would require stripping away a whole stack of interrupt armor to prevent a major attack much like the seizure-inducing barrier generating for Omega's ultimate attack in O11 (at least in normal).
