DLCs can be great as long as they are really extra content and not content which would be already in the game without this possibility. I mean, stuff like the Skyrim DLC in Minecraft wouldn't be in the game if there wouldn't be stuff like DLC so that I don't know ho you could complain about that but I think as example many competetive multiplayer games would already have more maps from beginning if they wouldn't know that they can sell you some of the maps they already created in a later DLC.
I think I never paid for a micro-transaction so that I can't really tell if it was worth it but it's pretty much the same with this, as long as it isn't something which would be in the game for free without this function it can be a nice addition for some people
