This is why I was fond of SL1's system. If you really wanted to be 'that guy' and change every time something more powerful comes up, you had to roll an entirely new character. Grinding for stats isn't a thing anymore, but I digress.

I don't see any mechanical solution to this being pretty. If anything, this should be discouraged via game rules. Godmodding isn't allowed, and being good at literally everything isn't a far cry from that. If there are people blatantly swapping classes on the fly to 'rematch at their full power', it wouldn't be difficult to encourage GMs to scold those people.
