Healing can suck even for people who have been playing the game unfortunately, i blame Gordias but that's a whole different story in itself lol

I would suggest maybe starting off with a dps to get familiar with the mechanics of the game but even than you will get blasted for low dps But generally tanks and healers recurve the most flack which aucks...

But try getting with an FC and running dungeons with them now a day's pugging dungeons as a healer or tank is an absolute nightmare
