The way we see it... we think the healer mana model for Cataclysm is sound and ultimately accomplished what we wanted... When players feel like increasing their skill doesn’t increase their success, they tend to get bored or frustrated.
But this new healing model is boring and frustrating.
Green bars go down? Green bars go up! I stay out of the fire, everyone is happy!
What is so hard to understand about that? I liked keeping the group at full, playing whack-a-mole with healbot in wotlk. I liked healing quickly and effectively with only riptide, chain heal, healing wave and lesser healing wave (and earth shield). I loved bosses like Stinky, where I was furiously filling green bars asap, to make sure I was ready for the next round of green bar filling.
What I don't like (enough to not even bother with doing it it / subscribing to the game for 10 months of this xpac) is this whole "healers should let people be half dead all the time, because it's about managing your mana pool, not actually healing people" mentality you folks dreamed up. Sorry, but that crap is psychologically unsatisfying, hence, as you put it, boring and frustrating.
Simply put, Blizzard:
Green bars go down? Green bars go up! Else, I'll hate healing in WoW and keep playing EQ2 instead, where it's psychologically satisfying and fun...
Disagree? Good for you. I'm entitled to my own outlook on life and what I feel is fun, thanks.
