I hope that this isn't the end for this map, because it is honestly one of the best sc2 custom maps, even if everyone if lotr channel hates it.
Some food for thought; this is not, strictly speaking, even a LotR-style map, but a diplomacy with heroes. They might seem the same, but there are actually a few vital differences in gameplay. The changing alliances, for one, as well as the lack of base sniping or recall (both present in virtually every LotR map). The objectives, as well, are often conflicting. LotR maps have the same victory conditions for every player: kill the other team(s). Here, there are wildly different objectives, where at least three players absolutely require King's Landing in order to win, even as it is irrelevant to the Night's Watch.
As for why the map is outright hated by some people (I don't, personally, but I am a pretty miserable failure at negotiation, and there are very few people who like consistently losing), my guess is that it is considered to be a map for less skilled players, owing to.......well, the lack of certain mechanics, as well as the respawning heroes. There are probably a few other reasons that aren't coming to my mind, though.
