i wish i could argue this with elliot, but as i'm still in act 2, i'd be talking a lot of non-sense (i know, i know. what's new??!??). you have to wait for 3 more acts! <img src="/ubbthreads/images/graemlins/stupid.gif" alt="" />
now, i don't play a mage - so i have no firsthand knowledge. i run an archer (hero) and melee DK.
however...i personally find archers to be incredibly more efficient than melee types, performing a good 85% of all kills (i truly find the dk worthless except as a pack animal). and i don't experience any problems inside or in closed areas (anyone remember josie in DD?).
my kill rate is a good 8 or 9 to 1 (bow over melee)...and if what elliot says is true '...a good bow was absolutely no match for a good spell...' i would have to imagine the kill ratio would shoot to about 15 to 1 over melee.
kinda makes you wonder why you'd have a sword........
honestly though, i believe whatever YOU are comfortable playing is the BEST choice for you.

did i sound sufficiently defensive of my archer?!? <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" />
