I like it better as a GCD reduction stat I just wish it actually had a reasonable impact, though if it also gave some TP regen in addition then it'd at least become more valuable.

I'd love to have more control over my rotation and be able to use my abilities faster to pump out dps, but as a result you burn through more TP. If they made SS reduce GCD by more than it currently does so it'd actually be useful as well as offer TP regen then it'd be nice.
