Agreed, gouge and between the eyes are to valuable for cc'ing off targets. Sub can still be good in the right hands, just falls a little short next to outlaw. It really get's it's teeth a bracket up when you get shadow dance.
My rogue was very close to your before I updated. With those GF'ed chants you can get to about 300ap with 3k hp. Here's my dorf rouge if you want to take a look.

As far as weapons go I prefer the 3.6 cudgel of narralex w/ landslide...
Landslide on the slow mace procs a lot. I think I've settled on LS MH/DS OH for my horde rogue. Still not entirely sure if it's worth it on the 2.6 speed Dazzling Longsword.
i played around with a few different builds. 3000 hp felt like the sweet spot to me. i wouldnt prioritize versitility, but also wouldnt avoid it. for example the falcon ring and assault band give the same tooltip damage reading.

This set feels comfortable to me. Haven't played since the proc nerfs though.
