Honestly, be prepared to be frustrated, especially while you're learning to play a healer in PVP. Not always. Some runs are fine. But, some make you want to scream. I say this because you will always be the number one target. You will also be the one who will have 6 enemies attacking you at once. You will get stunned constantly. You will be put to sleep constantly. You will get chained to an opposing tank constantly, unable to get away.
