Any class should be able to kill any other class in a 1vs1 situation. As it was 2vs1 there is no reason why the shielder should actually win, unless the 2 guys fail in teamwork and can't fight.
Two shielders will hardly kill a lancer who knows what he's doing, on open plains map, of course.
I'm not saying that two archers shouldn't have a chance against a shielder but those chances should be lower than they are now (pretty damn high).
I really don't like current class balance and roles those classes fill. I've made so many threads and posts and never got any support from this community. Might try it again.
Basically I want kiting archers gone for good and replaced with high damage (but without armor ignore so that armoured guys don't take same amount of damage as low armoured players), decently armoured archer who's decent melee hybrid too. I want to see other popular classes changed (including mine).
With this balance we have for over a year now with minor changes, people get bored fast. Change some things, please developers!
