I feel I must reply to the poster above mine, because you're simply put..wrong

Imagine you played bard at level 60 (last expansion, a reasonable assumption) and you leveled to 70, not completing your lvl 70 class quest to get refulgent arrow, which is a new ability. Troubadour does nothing for your DPS and the other skills are dots last longer, which one can argue doesn't necessarily effect your DPS in the same way as getting new rotational abilities does, we agree?

Splitting post in two, because 1000letter cap.
