2.0 2ndary stat weights were rougly .33 . They are now roughly worth .09. In addition to that Spell Speed does not reduce your GCD nearly as much as it used to.
In full i180 our gear = DarkLight from 2.0
Supposedly the stat jumps going into i190 and higher, will be significant. It all remains to be seen.

I believe they are trying to prevent power creep, and essentially have reset us to baseline with i180 gear.

But as things stand now, secondaries are pretty much worthless. You could be 200+ over the acc cap, and only be doing 1-2% less damage than someone who has those secondaries in crit or det.

Pretty silly eh?
