Random pug healing...finally.

Yeah, so I finally did it. Yesterday I signed up for healing heroic VH. Easy. Just wanted to get the fingers going. Then I sucked it up and entered the queue for a random...as a healer....yikes. So hilarious that I was actually nervous...lol! Anyway, I did breathe a sigh of relief as the screen for UK came up. Zoned in and I asked the tank to go semi easy as I was a new healer. He said no problem. Then again there aren't any really big pulls there. Most of the pulls were 5 or 6 mobs. Pretty easy. I'm glyphed with water mastery, LHW and RT. For the most part I just keep my earth shield up on the tank, RT(+85 sp per, stacks x3 for 15 sec.) and LHW as needed. Of course I use chain heal quite a bit too, particularly if I have a melee heavy group that is taking alot of aoe damage. I wish the cooldown on RT was shorter. Do the other healing classes HoT's have that long a cooldown (6 secs I think)? Anyway, now I'm wondering if the glyph of chain heal is a better deal. It seems the glyph of LHW only benefits the tank (+20% heal when earth shielded...i think?). Any wide aoe, it would certainly be nice to have a 4th target for CH, but then again that's assuming all are within range of the bounces. Any shammies care to add? So the UK run went fine. No deaths. Easy instance though. Queued up again and got HoS. Made me a little nervous as this instance has a layout that allows for big pulls. Again asked tank to "tank it easy". He said no problem and pulled the entire instance in 3 pulls instead of 2.....Things went okay though. No wipes, several deaths. Lots af aggro running around. Tank couldn't hold very well. 3 melee so lots of damage to heal. I was majorly lagging as well. All things considered I thought it went quite well. Suppose I'll hit random again today and see how things go. Fingers crossed!
