Tier VII is the last Battleship tier where BBs there get Overmatched by typical guns found in the tier.

Matter of fact, all Mid Tiered BBs are vulnerable to 380mm+ Overmatch. The issue about Nelson getting Overmatched by 380mm+ isn't a rare thing. If you're in a CV game, you better not be out alone, a decent CV player will know your AA sucks and will go after you if you're alone and easy pickings. Don't be surprised if you eat a bunch of surprising Citadel hits despite being well angled. The bow is so big that it can't be helped to hit it. You think you're sufficiently angled against a 380mm+ armed BB opponent, but you're really not. Her extremities are big, particularly the huge bow, and it's vulnerable to Overmatch by large AP shells. Not the fastest in her Match Maker bracket but you're not Colorado / California slow at 21kts or below. If you know how to tank as a BB player, and know how to protect your Citadel, you'll appreciate Nelson's staying power. The fight wasn't even close, Nelson was winning that easily. I remember getting into 1-on-1 fight with a competent Nelson player using my King George V, a ship I'm very confident with. She can tank their AP, Overmatch them with her own 406mm AP, and easily outlast them with the Zombie Heal. + The combination of the 406mm AP, Zombie Heal, and proper defensive sailing means Nelson has a very big advantage against Battleships armed with guns smaller than 380mm. It's actually a war of attrition that Nelson players can win against DPM machines. While doing so, she can chuck her shells back at the Cruiser, who have to worry about 406mm AP Overmatch, and that most Cruisers she encounters lack Repair Party. Because the Repair Party heals back so much, and all Repair Parties heal 100% Fire / Flood damage back, Nelson bounces back real strong. Cruisers will try to leverage DPM attacks with Pens and stack it with Fire Damage. IMO, this heal makes her dangerous for Cruisers. If the Nelson player knows how to protect her Citadel and limit enemy hits to Pens / Overpens, they can really milk the survival of the ship for a very long time. + Super Stronk Zombie Heal, as long as you're not eating too much torpedo / Citadel damage. + Solid 406mm AP shells with great Overmatch benefits for the tier. + RNBB HE shells melt things good, have equally nice Fire Chances, and have very high HE Pen.
