Displaying support for a favoured mob is fine, but demanding people "should" do what you want isn't reasonable. Everyone has their own opinions and different preferences and reasons for liking whichever one of these mobs, and they should simply vote for whoever they want.

Info should at least be factual in support of one's choice over assumptions. It's uncertain exactly how the rascal's mechanics would be (how the "hide-and-seek" behaviour would work, its spawning conditions, its loot table, etc). Whether they're farmable is questionable, because there's also a possibility that they will despawn after their mini-game is done and could randomly spawn again in another place. Where there's lacking confirmed data, there's no determining of some potential ideas beyond what we do know. Since these mobs are fairly minor additions, not much can be expected in terms of utilisation. We only have the facts provided by Mojang to go by.
