Went through my spell page tonight and I only have access to the Flash Heal and the Power Word to help absorb damage. I keep it up on the Tank constantly, although I've found the lower level dungeons I'm going through aren't all that difficult, as long as I pay attention. From the looks of things I won't get a Heal over time ability for another couple of levels. Thanks again for your advice.
I was never too worried about being called a bad healer. I am leveling a tank for the first time as well and sometimes things just go wrong. If it's my fault I'll get some feedback and learn from it. Otherwise the ass-hats (as they seem to be called on here) don't phase me. Thanks again.
