i feel like combining the current system (or reducing the SP, but not the favorites) with a system of voting in batches works nicely - however, OzzyOzrock's point definitely is important
a quick search on osusearch only yields 37 unranked maps with at least one mania difficulty that have over 100 favorites, some of which are mixed sets, which might indicate that 100 is a bit steep for mania, and i'd be willing to bet that other non-standard modes also have similar difficulties.
it's also been proven, at least with regards to mania, though i don't doubt it's happened on other modes as well, that certain beatmappers have the power to abuse this concept of "loved" maps; i know of two maps in mania that had 100 SP dumped right onto it for the purpose of loved, one of which was the beatmapper of the map being loved in the first place; imo, the map wasn't all that great, and it certainly doesn't epitomize what the community "loves."
the number of favorites, imo, can be raised, because it takes much less effort to get a player to favorite your map if it is enjoyable. it doesn't take a detailed playtest and propositions of revision, it takes a playthrough and a click of a link. boom. something like 75 favorites might be a good middle-ground for all of the modes.
to counteract the SP reduction and make it possible to still keep the requirement at least respectably difficult, here's an idea: set the minimum SP to some value less than the current; 50 or 75 seems ok for this, however, put it under a contingency that no single user (including the beatmapper) can commit more than a certain fraction of the stars required for loved. 50% seems like an alright number. doing this requires the beatmapper to seek additional endorsement for the map - beatmapper has to commit SP, but also has to get others to do so as well. increased favorite count also makes it so that they have to seek more people to get the map to the status the desire.
just some thoughts.
