There are plenty of other classes, gladiator, tyrant archer, Of course mages are going to be most powerful in the beginning of the season they always are.
Not to mention archers are not even all that bad to play right now, even without focus. I got crit by a GS for over 4k.
You should not be able to tank an entire faction while dealing these ridiculous amounts of damage, it's fucking insane. Who wants to spawn only to be fucking targeted by 30 daggers? Anybody else find this fun?
