I feel like the only real point in having a vote over a predetermined set of maps is precisely because the larger community wouldn't understand creative/unconventional mapping if it hit them in the face. When half the maps in the pool are the garbage maps that, in the absence of this voting system, would be the focus of the community anyways it sort of defeats the purpose of it.
If the maps are going to be largely inaccessible by the larger community then Toy makes a great point. People will be hyped to see top players playing difficult maps to begin with. Why not select the predetermined set of maps to be those that top players are actually excited about and want to play on a regular basis and then use the vote to allow the plebian community to select from those the maps they would be most excited watching people play?
I think people are confusing the purpose of the loved section with the purpose of this voting system. Sure, the loved section isn't supposed to be about quality and it only really matters that a lot of people are excited about the maps. That's just stating the obvious. It's also pointless to have a vote like we do now to accomplish this simple goal. As Ephemeral has point out, if the community is willing to meme a map into the loved section by spamming it with favorites then it probably deserves to be loved by virtue of what the loved section stands for.
That is not to say I think we should get rid of the voting system. Rather, I think the voting system should be used as a means of adding more sophisticated maps into the loved section that top players are interested in while still maintaining some level of community input. People have already mentioned the positive affects that giving such maps loved status could provide so I'm not going to bother rehashing that here.
The details would still need to be ironed out on how to select such maps for voting but it would likely require a voting/suggestion system restricted to top players by which they could select/vote on the list of maps to use in a 2nd round of voting open to the entire community (similar to what we have now).
Tl;DR: Current voting system is pointless due to maps selected. Overhyped maps should be added to the loved system by another method and voting should be reserved for interesting/unconventional maps that top players actually want to play.
