Oh, we got a statement in Dev Q&A!
Tim: I believe such concerns regarding RNG have been addressed several times already (though the last time may have been a long time ago)? From my perspective, I can say there is simply no need to tweak the chances in such ways in the game. It’s by far best to keep the system as simple as possible when it comes to RNG. This has been the case from Day 0 of the game’s development; the game is already so complex that doing anything unnecessary with any of the odds would just create problems for us.
So… when a fighter revives six times in a row (0.073% chance), or all five enemies dodge twice in a row (0.034% chance for cKadilen), then that is just randomness (or a bug that devs are not aware of). Ok, I am happy and I can live with this
