Ninja stat optimization

[Viridiana]

So, I've been gearing up my ninja in anticipation of hitting FCoB and I've been wondering what stats to focus on. So far I've been focusing mostly on determination while making sure I have enough accuracy but everyone tells me I should focus skill speed, butthat just feels like iit'll cause problems during long fights even with invigorate. Thoughts would be appreciated!

Skill speed is our least useful stat. Point for point, Det wins, but you'll basically wind up with a det/crit split and a splash of skill speed.
