Yes, bards specced for healing, can in fact heal. Maybe not as well as well-geared divines, but certainly enough for SHROUD on NORMAL. And even that, a well-geared and well played bard outheals 99% of pug clerics. You don't have to leave the group just because we only have 1 divine.
Oh, you joined the other shroud LFM that was just posted? Congratulations on being inconsiderate and wasting everyone's time, especially the people who waited the whole time for the group to fill and were left out. How nice of you.
