IMO, it's pointless to ask people that are actually playing a mage/archer.
No offense, but those that are playing a mage/archer are almost always going to vote for what they play. That's ... why they play them right? You don't want yourself to be in a party? >.>
I think mages and archers are evenly balanced.
All the KM parties I've had with a mage has failed. Of course, it's mainly based on the person, but the mage always spam skills really quickly to draw aggro, die, and then blame the cleric, or just stand there and do nothing at all. Or the guy uses that lightning spell, which just negates my bleed =.="
But when the mage gets the 20 second fear spell, and their nice little spell that burns the mana right off our shoes, who'd want an archer? Who gets three AoE spells, the essentiality for leveling?
I don't really mind what party members I have (well, a cleric please >.<). Archers and mages are all the same thing to me.
And I believe we have stronger DoT than mages. I mean, if a mage dies, they don't exactly have lasting damage effects (not debuffs, actual damage). While if an archer dies and already put poison and bleed on an enemy, that damage will continue to go on the enemy (though not for long .__.)
