if you thinking on to be d2 d3 then i say no because you can get lazer sword very usefull vs wizard.piercing just give more damage like g1.5 it dont do a big diference like a 2h weapon and need dex.if you dont care about dex and want a litle more damage then change.graple is nice sugestion too because only need same str as piercing and no dex so you will have a lot of points free to add on full con and some endu or maybe cha.well in my opinion i say dont need to change but if you like damage and want more and more then change now
