I have two independent legacy questions.

1/ Whirlwind of Steel. Assuming a human with 23 dex. In the context of PvE only. Is impale's -6 dex enough to make "good use" (obviously loosely defined) of the Whirlwind of Steel legacy? (I understand that ideal situation is 25 dex vs. 3 dex, but I still want to get a sense whether ~9 or so dex differential is sufficient. 9 because I assume mob's average baseline dex at 20 + -6 from impale = 14 mob vs. 23 human dexterity.) Would love Daev's thoughts on this.

2/ Fluid Deceptions.

a/ Am I correct that the auto-feint is int based?

b/ Am I correct that two-attack manual feint is simply skill based and is not keyed off any given stat? In particular, I'm curious whether a giant with 16/17 int can take good advantage of Fluid Deceptions in a defensive build by relying on manual feint...

Thank you very much in advance!
