I actually enjoy the new healing model its much more entertaining than. "PoM, bubble/FH spam" that was wrath. It makes me actually think about what im casting/going to cast (I actually have to pay attention). It also makes everyone focus on not taking damage they dont have to.
If you want "spam 1 button = win" get with a group of like minded people and turn your xp gain off at 80 and just run wotlk forever. In the meantime the rest of us will enjoy the use of our brains.
I continue to read Q after Q after Q and what I see is:
They don't have time (read patience) to run a heroic that might take a few hours and requires CC or thought.
They don't want to manage overhealing, stop overreacting to damage and spamming everyone up.
A general unwillingness to work with the mechanics, HOLD YOUR DPS AND TANK ACCOUNTABLE for their failings when it comes to damage taken, or learn the new system.
Wrath healing was stupid and boring. I shouldnt have been able to walk into 10 man ICC, solo heal Heroic Marrowgar at 19k hps and laughed at my ever-full mana bar while doing it.
Now, I have to think. I have to MAKE people use my lightwell, I have to not overheal or refresh a hot that doesn't need it. I HAVE to dispel that horrible ticking debuff.
Cata right now is soooo much fun...please Blizz, please don't let lazy people who hate interacting with people in groups and are too afraid to tell a dps and/or tank they are doing something wrong ruin my experience...pleeeeeease.
