Migraines, healing, grid and healbot...

Okay, so my intent was to post my thoughts on grid vs healbot yesterday. Unfortunately I was sidelined by a migraine. I've only had one other migraine in my life, about 7-8 years ago. For those of you who get these anymore than once per month....I bow to you and offer my sincerest sympathy. I don't get headaches in general that often, but when I do they're usually not much more than a nuisance. Migraines however....man, that knocked me out. Fortunately I only had morning appointments so was able to leave the office and sequester myself in a room with some painkillers and no lights until it went away. Needless to say, I wasn't feeling all that great so WoW wasn't on my list of priorities. A little later in the day I did get in a random 5 man on my shammy. Which leads me to the second topic in my title....healing.
I am still a relatively new healer. I'm no longer at the bottom of the learning curve, but certainly not at the top yet. Truthfully I have been known to drop a group when the HoR or PoS loading screen pops up. I just haven't felt ready to heal those. And I figure the group is now in front of the queue so they'll replace me in less than a minute...no harm, no foul. Yesterday however was different. I queued for a random as a healer and sure enough up pops PoS. I let group know that I had not healed this instance and they were all okay with it. Everything started out quite well. Moved through the trash without any problems. Got to Garfrost and finished him off no problem. Of course it was after Garfrost that I realized I had entered the instance without any mana restoring beverages....duh. Fortunately mana regen with water shield and mana totem is pretty fast so again group was okay with my noobishness. Moved on to Ick and Krick, one shot. Easy. Everyone did what they needed to do. Cleansing totem was a great help and despite retpally dc'ing during fight we still did it relatively easy. So far so good, I was feeling pretty confident. Of course its the mobs on the hill as you move up to the ice tunnel that are the real test. First group, tank falls off side and loses aggro...which quickly shifts to myself and the others.....wipe. No problem, we dust ourselves off and get back on it. Tank marks everyone this time and we knock out the first group. Hate those fire guys man...they are killers! Mark second group and finish them. Then we move on to the skeleton guys. Thinkgs get a little laggy and I don't get a heal in time and tank dies...el wipo (that's spanish for "wipe"). No problem, we're all okay finish off the rest of the skeleton yucky melee and caster guys. We get to the tunnel and all run for the middle plate/disc thingy. Tank spams thunderclap, I throw RT's on as many people as I can and we easily make it through the first wave. Then tank decides not to wait for everyone (not sure why???) and start second part. Myself and another caster who were getting mana are left behind...result....le wipe (that's french for "wipe"). Tank apologizes, we rez and everyone arrives at tunnel entrance and for some odd reason the tank starts in...ZOMG! We're all at half health and half mana, but we manage to pull it off. We agree to one shot tyrannus which we do actually quite easily. A good learning experience over all. Thanks to the boomkins colossal dps (retpally and spriest were not so stellar, but not bad) we made it! I had just changed my glyphs too. I now have earth shield, LHW and CH. LHW works perfectly for the other 5 mans, but for these ICC 5 mans, it's definitely underpowered. You must use HW. Fortunately with the speed buff from RT, HW works very well. Big heals, relatively fast. I am considering changing to HW glyph instead of CH glyph. Totem choices for PoS. Obviously the cleansing totem for the ick/krick fight (I use mana otherwise). Wondering if the frost resist totem is useful and if so do the benefits outweight the loss of the flametongue totem (my default fire totem). Otherwise, stoneskin and wrath of air for the other two.
On to the great grid vs. healbot debate. Crankyhealer pointed me to a great comparison that had already been written by Keeva at Treebarkjacket. A better and more thorough comparison I could not have written. The only thing I had to add probably has more to do with clique than grid as grid and healbots frames are pretty similar (grid being a little more modifiable with addons). One of the things I didn't like about clique was that binding spells to an unmodified left, right or middle mouse click leads to all kinds of problems when using those buttons for their other ingame uses. It is possible that I have not figured out some modification that makes those functions only apply when over a grid unitframe, but not sure. The mouseover click feature of healbot is smarter so it literally only applies when you're over a unitframe. This means you have more possible mouse key bindings. For me, shift and control are the only easily useable modifiers, so that gives 9 bindings on healbot to cliques 6. I use a combo of keyboard and mouse so it's not a huge deal for me particularly with the limited shaman spells. Priests however have just under one thousand spell choices, so having those truly functional extra three mouse click bindings is really nice. As I said, I may have missed something in the setup that negates all of what I just said, but for now that is my two cents (for what it's worth!) on the topic. Again, check out Keeva's post for a really nice, easy to read and thorough evaluation.
That is all.
