A few are definitely better than you've heard.

Let me know if I'm wrong on any of these, but based on what I gathered its the WSs in the last section that SE needs to fix
Upheaval is an absolute monster when used under the effect of Mighty Strikes, and does pretty well otherwise. Since any weaponskill that Great Axe/Warrior gains will be situational at this point, that seems good enough to me.

Shijin Spiral looks to be the weaponskill of choice for times when Impetus is down. It has a small attack bonus rather than the standard penalties that come with most of these weaponskills, so that helps a lot.

I can say with confidence that those two are useful.

I'm not sure how much Apex Arrow has been tested, so I'm hesitant to say it's good just from looking at the fTP. My guess is that people complained because they were expecting Apex Arrow to make like Jishnu's Radiance and scrape the anti-life equation into the evil crotch of whatever it was used upon.
