If it's 10v10 and one archer is kiting 8 people, there's nothing wrong with that. Those 8 people could go and attack the other 9 people on the enemy team. The only time a kiting archer would EVER be a problem, is when they're the last one alive. Otherwise suck it up buttercup, you're doing something wrong if there's more than a few enemies left and you're chasing someone who's faster than you.
Archers should have to make that difficult decision of deciding to go pure archer, or be a hybrid...just like every other class. a pure 2h can be very useful in melee/duel's, but a 2h/thrower hybrid is going to be more versatile in more situations, but his 2h isn't going to hit as hard or as fast as if he went pure 2h. That's the beauty of c-rpg, you get to make those tough pro/con decisions.
