Archer viable?

Played this game many times, always gone mage or 1h/2h+crossbow. Now im playing it archer for the first time. Do you have any tips, bows locations, does strenght empower my attacks with dex based sword? Ive cleaned most of khorinis, skipped just the hard mobs like shadowbeasts, wargs, skelets etc and this is my setup right before entering jharkendar, this sword and composite bow with 60 dmg i think
