well, this depends on ur equipment. if ur planning on using ik maul, i would recommend using the rest of the set as well (- helmet of course). if i remember correctly, should give you +450 to ar and quite a bit of dex as well. throw in a raven as well and you should be covered.
well im still a pretty low level so I don't think I can have IK maul, but so far i didnt put 1 point into dex and just wondering if i should or shouldnt...
i dunno if u should or shouldnt, but i can tell you that i have a lvl 90 ww without a single point in dex, and i dont think he has problems hitting stuff
