It's long hit me as kinda funny how often people underestimate Berna's defenses. People just see "rogue" and squawk about RNG but evasion is actually a pretty nifty complementary defense when you're talking about a unit that already has static defenses roughly on par with a Platinum princess. 50% is unreliable in terms of surviving a one shot kill but when you're talking about a unit that can already survive 3 swings from most opponents that 50% chance can be interpreted as a 93.75% chance to require least 5 swings instead of 4 before dying. She's not super impressive by black standards prior to skill awakening and dat wave clear but her raw stats already make her far more generically useful than the other rogues.
