There are versions of PR that mitigate this issue. Mixed-member PR sacrifices a little bit of precision in the proportionality, but limits the seats assigned to party lists to only some additional ones used to balance out the un-proportionality of the results. Most of the elected body is not from party lists.
I’ve not heard of that one before, but I can see the reasoning behind it. Is there a name for the system that I can look up?
