Exactly. It usually happens in laggy scenerios. It procs but the skeleton model delays behind the actual proc and you remain in human form for a couple of seconds. This causes the lock-out. If you lucky your weapons become hidden or you hold wrong weapon in wrong bar. It's just buggy from everywhere.I doubt it possible to fix it without changing core visual effect. When you transform it like game loading new model of character so it force-disable you coz it need to load it and then continue char action. And when lags and fps drops hits - reciever end slower updating model and not start to act before complete - it cause disable to be longer than just second. This was happening in cyro for years when in large battle you changed weapon types thar have different models. Happened with outfits when they launched.
Not to mention that due to proc condition it will proc in pve at moment of higher pressure and, as tanks who tried it in trials knows, resulting in instadeath.
