Yeah. It doesn't need to be easier. It needs to be more fun.
Oculus isn't that hard. It already ranks well below ToC, HoL, or AK, but those aren't nearly as annoying.

There's not much they can do to make it less annoying without completely changing the mechanics of the instance. They'd rather put that time into working on Icecrown/Cataclysm/etc., so I understand.

At this point they're doing all they can do, make it easier so it's as painless as possible when you're unlucky enough to end up in Oculus on a random pug.

The annoying part isn't the mobs, it's getting mixed up when flying. It's difficult to get back to your team when you can't tell what ring they are on.

I vote for an arrow pointing you towards either your group leader or your current objective. Barring that, I'd say some way to tell what distance people were from you vertically based on their icons on the minimap would be very helpful, say darker for lower and lighter for higher. This minimap thing could conceivably be helpful in other scenarios as well.

I'm Docp and I enjoy Oculus.

There, I said it.

Why do I feel so dirty.

This; the instance maps are getting better, but a 3d minimap would be more functional. Descent had an excellent wireframe minimap back in 1995 that would suit the purpose of Oculus and other multi-level instances well (think LBRS).

I like Occ, it's the only 5man with any challenge anymore. It especially rewarding to get Ruby+Emerald Void on five Ambers, I guess it will be a little less so after this patch.
