Yes. If a new chain is skipping on an old cassette, the cassette needs to be replaced

cassette doesn't look bad, I would make sure your gear is index properly and your lines are in good condition before pulling out the wallet for a new cassette

See the wear on the smaller gears? It almost looks like the edge of the teeth squished. Thats what got me thinking new cassette.

It looks like ramping teeth that shimano uses for smooth shifting to me tbh

I bent the derailer hanger out a bit and it seems a lot better now.
