Just throwing out an idea:
Stuns fill only 100/sec like the mez and you get additional resolve based on the damage you suffered while stunned. When you get full resolve this way you unstun.
Every stun has a maximum damage it can ignore before it breaks like a mezz. The amount of ignorable damage is dependent on the accuracy stat.(Let's give accuracy stat some love)
Honestly, I'll take ANYTHING over what we have. So yeah, I support this idea too...ANYTHING would be worth trying at this point.
