I'm not bothered by the fact that you lose stuff to level sync. That's expected. It's not quite fun, but I do not ever expect them to change that.

My actual issues with content that isn't Dzemael Darkhold onwards is that there's just not enough actually happening. Tam-tara normal is the worst of it, with literally only about one boss fight the entire time and every other 'boss fight' being no different from the rest of the trash mobs. But even then, a lot of the dungeons are dragged down by simply having too many trash mobs filling space, which aggravates the whole "we don't even have an interesting rotation" thing. They're just not fun. Which is unfortunate; there actually are some mildly entertaining boss fights sprucing things up as early as Haukke Manor (and steadily as of Brayflox onwards), but show me someone that wants to actually struggle through the mess in Stone Vigil normal.
