On my Rad/SS tanker, if I'm herding mez heavy spawns like Carnies with their swarms of Illusionists or on MSR I might get mezzed, but due to mez resistance, it drops so fast that if I don't notice the red text, it feels no different than a spot of latency. Since Beta Decay is my only offensive toggle, it's easy to not notice that it dropped.
However, it's possible that you are seeing something different since it's happening on your Blaster too.
