I recognize this feeling….Tis extremely stressful at times and u often feel insufficient. Its very easy to burn out as a healer. I still enjoy healing but I love to dps/tank now and then for a change. Tho the only reason I still enjoy healing is that I play with loving friends and a warm hearted guild, both in ESO and ArcheAge.
