lol omg wrath was just spam big heals all the time with no thought of mana god forbid changes came into play to make healers more mana aware OMFG get the hell out of here i cant just flash of light spam anymore OMG OMG OMG OMG OMG OMG bliz you screwed us over
get over your QQing and learn to addapt to the situation that is at hand
hmmm two points here
1) I loved the changes they made when I was in a group that was competent. One that used cc etc meant that heroics did tend to feel more like heroics. Challenging but doable
2)Blizz wanted to bring cc in . So it was meant for all classes to up their game. Not just healers. i was personally disappointed when WTOLK came out and my tank was constantly told not to cc, just aoe everything.
We don't think blizz treated us badly, it was the player base. Players like yourself most probably.
