So, I've been back about a week now. I'm enjoying playing again, especially since I dinged 84 and switched back to healing (leveled as kitty, but I need to get my tanking geer and skeelz up to snuff). And I must say, healing is WAY better.
It was so BORING in WotLK to heal. Spam a bunch of HoTs on everyone and relax. Don't worry, you'll never run out of mana. No cares about overhealing, mana consumption or anything else. Faceroll haelz! I love that I can actually run out of mana. So, I've developed two rules for healing in Cataclysm. So simple.
1) THINK before you cast!
Sounds simple enough. This means actually knowing which spells do how much healing and take how long to cast. Actually, this can be tough for some people, but I guess if you don't want to take the time to read a tool tip, you probably aren't taking the time to read this post either, so I'm not talking to you people. I don't want to go into any class specifics because if I did that, there would be more than two rules, so you're all gonna have to do the thinking for yourselves. *GASP*
2) If you do run out of mana, BLAME THE TANK for not having enough mitigation/avoidance!
I cannot stress this enough. It is NEVER your fault! Healers are just too f-ing awesome to be blamed for anything. And remember, tanks can take abuse... especially the bears because they tank with their faces. No one likes tanks. They're the bass players of MMORPGs.
P.S. If you're a tank and you're reading this... I'm just kidding guy! All in fun right? Love you! You can stop reading here......
Everyone else: seriously, tank's are sooooooo dumb.
