Hungary’s system is half proportional, half FPP on steroids, but it’s just as bad as FPP since our FPP lets the winner not just take the seat, but also extra votes into the proportional part of the race.

So, no, the EU is fine with everything, the only thing is that EU citizens have to be able to vote in local elections wherever we live, regardless of citizenship. That means if you join, and I rent a place in Toronto and move in, I get a vote for the Toronto mayor on day one.
