Not really. Read:
Ever gotten opened on by a concealment operative that didn't crit anything? Yeah that damage is laughable.
When Hidden Strike crits though, the opener is at about the level it should be.
And it wouldn't be the first "autocrit". We have them as assassins too. Through an ability called recklessness.
Given it's hardly a real autocrit because of current crit levels.. but it should be. And that works just fine. As it should.
Autocrit is not necessarily bad or OP.
Recklessness only affects force. Assassins rely on maul for burst.
