Ehehe... the Archer issue always keeps coming back. xD
Back when I was an Archer I probably had the lowest damage in the group cause I was a DEX Archer too. But y'know what? I didn't care cause I was sure as heck able to keep aggro on MD and live through it too. Not to mention able to solo just as well as the the next Archer who went full STR.
And like lvra said forget about those rude players as they're not going to change. Be the bigger person and just ignore it. As long as you're having fun playing your character the way you want... everything else really doesn't matter.
Heck if you wanted you can play a full STR Mage if it's your thing. xD Seriously, might as well do that with all the godly STR Mage equip the mobs drop these days.
