Is Vayne's Silver Bolts + Fan The Hammer true damage working as intended? It's genuinely unplayable as an enemy tank.

Fan the hammer applies on hit effects at 20% effectiveness per missile. But because Vayne's silver bolts are true damage it just does the full damage.

Played a game as Mundo where her autoing me once would fully trigger her silver bolts twice. Then she rolls to another angle and does it again. Basically any time I was on the same screen as her I'd die without any real counterplay.
