Resolve is stupid and here is why:

Lets say i throw a flashbang(8 seconds). It immidiately puts the resolve bar at full.

By the time the flashbang wears off, your resolve bar has gone down.(all you need is less than full).

Then another person throws a flashbang.

what should happen:

You get less of a stun, or no stun
-----------------------------

What actually happens: You get stunned for the whole duration
--------------------------------------

Resolve isn't put in right, it "builds up" on snares and stuns, and sometimes gets full. But you can get anyone stunned/snared for the ENTIRE duration so long as their resolve bar is not 100% full.
