Not so much an unpopular opinion as an unpopular taste: I want a game with the smart good stuff from class and level games like various chunks of D&D lineage, 13th Age, etc etc, and/or various versions of WHFRP, with cool magic of various sorts and multiple species of PCs and lots of room for adventure, but with very little combat. I want characters to go places, meet people, uncover secrets with minimal bloodshed - often, none. But designing such a game in which almost all the combat-related mechanics, advice, and setting elements are outright replaced by other things is apparently not a thing to do.
