My only major concern over PR is that I kinda like being able to vote for
my MP rather than having to vote purely on national issues. Having an MP assigned to my constituency based on other people's votes isn't a great thought.
They have to be careful. I would be more interested in balancing the constituencies properly for now, along with some other reforms to make things somewhat fairer overall.
Going pure PR doesn't appeal though. A hybrid FPTP / PR would be ideal though I've no idea how that'd work
