Bloodmoon Fishing is absolutely infuriating and needs major alterations in a hotfix. It's an event that's significantly unlikely to occur, with rare and extremely difficult enemies combined with a mob of regular enemies, which then have insanely low droprates for items which are mostly weak in the first place. Even the summoning item for the bloodmoon itself is insanely rare. Everything needs to be more common.
World Globes are a really good idea but I despise the fact that they're A. totally random and B. totally expensive. I could deal with either of these but having them together means I've dropped multiple plat trying to customize my backgrounds. Just let us choose the ones we want or make them dirt cheap please.
So far my experience with the happiness system is that it is an inconsistent mess that isn't indicated clearly enough in-game and doesn't work correctly half the time, stifling building creativity. It needs to be far more lenient on NPC distance to/from each other especially.
