General feeling is stick with bio-chem for now as Armormech/armstech, seem only good for lvling. The best gear atm comes from pve hardmodes, and upper reaches of pvp gear. I am an armor and love it but i know when i pvp sometimes want those reusables. If you want to do armor just make an alt for it, what i did with bio.
Thanks for the tips, my Commando is still only lvl 29, so I would have us for it while lvl and to give to compaions, I don't think I will have the time or energi to do high end pve stuff :P But will I have any use of it in end game at all (gess I would do most Pvp and some flashpoints and so in end game)? or would I just make a bad decision? :O
