So far the way it is now works for me, raids are there for when I want to participate in hard content. In regards to difficulty the main thing I would ask for is more challenging dungeons post cap, I mean most of them are easier than some of the leveling dungeons.

Doesn't need to be raid hard but just harder than what it is now. IMO you should only be able to pull trash in huge groups when you outgear the content (like castrum and prae for example.)

Some actual mechanics in some trash would be nice, the original CT did this in between each boss but ST barely had them and WoD was better in this regard but still not as interesting as CT.
