I don't think bard is a full support neither should be, as a archer upgrade, doing substantial dps should be his main focus, but since he learn the ways of bard after some time, he also should learn to manage his time to input some support in the battle, just as he is right now.

In fact thay they should do is give bard some kind of hast song with 30% penalty on dps and we would keep it almost full time and have our lowered to a point other dps wouldn't feel treat and qq about it.
