My hm hunter (pve only right now) is 2dex, 5luc. Grinding is slow at first, but right around level 30 my crit rate really took off. currently 33 grinding map 3, killing reds before they get close.
unless you are going for 1-15 pvp, you don't really need str. You will need at least 475 luc for 95% crit rate, dex for evasion and accuracy (also increases ranged damage.)
Oh yes, and keep piling on the luc, as it increases critical damage.
Hope I made sense and was helpful.
