WHY ARE YOU PLAYING A BARD IF YOU'RE NOT GOING TO SING?!

[Moqi]

Then I'll do the same:

If You are running out of MP as a healer in DF, You are a bad healer.

If You are not passing DPS checks in DF, Your teams DPS sucks.

If You are dying (thus needing TP or MP Song), you suck at dodging.

It doesn't matter... i could say the same thing as a healer and not heal outside of tank and unavoidable damage because you should avoid everything else, but I don't, because it's a disservice to the party and isono help to anybody. Someone being bad doesn't make you good: if a whm needs a song and you don't sing it because he sucks at managing MP, you're just as bad.
You're playing in a party, act like it. Your high dps is useless if the rest of the party is incapacitated by your lack of singing. It's not that hard of a concept to understand.
