This might be the reason for archer to become Bard.
Archer right now does insane amounts of DPS while staying away from dangerous AoE, wich has led into the GLA/CON/CON/ARC/ARC/ARC/ARC/ARC partys for dungeons.
Why should the archer be able to do this? Why can they stay safe while outdamaging all other DPS?
The answer is: They wont anymore.
Archers will have to attack while also keeping up songs or whatever they do as bards. This will lower their DPS and posibly enhance the other party members DPS making them balanced with all the other DD in the game.
I've been playing archer lately and i found that my positioing makes it extremely easy to target my pt members and heal them in case of emergency. The position of the archer is highly suited for the role of a bard wich will most likely enhance party members with songs in the middle of the battle while shooting arrows.
