FFXIVs bard should be something like this.
I'm not going to say that archer turns into bard, because we don't know the facts. All I'm saying is if/when they put bard in the game, should be something like this.... http://www.youtube.com/watch?v=TNRkkVJiuVE Bard kinda sucked on Mabinogi, but it was the best implementation of it I have ever seen. That's all I did in Mabinogi was bard, had soo much fun with it. I know it would be hard to do something like that, but a boy can dream can't he?
Note: This thread was made when we didn't know who was going to be bard.
Doesn't change the fact that making your own music would add content/fun/freedom/immersion.
