Rogue -> Assassin or Enhance option on my R-Grade?

What should I go for on my Immortal set? Assassin or Enhance?

Enhance has STR and P.Atk which as I heard is a better option fully buffed than Dex?

Apparently so, until Tauti.

P crit/ chance does not influence skill crit = useless
P crit damage does influence skill damage = uselfull
