Wait so now you want me to stand in the what?

For a long time the standard rule of raiding was "if the ground changes color MOVE".  It was a nice rule, simple, easy to remember.  However in the time honored tradition of tweaking the player base for their own amusement, the Blizzard developers have thrown us a loop in Cataclysm.   Suddenly there are good circles, things you should be standing in.  


Take a look and learn your new happy places.

Effloresence, Resto Druid

When you heal with your Swiftmend spell you also sprout a bed of healing flora underneath the target, healing all nearby friendly targets within 8 yards for 30% of the amount healed by your Swiftmend over 7 sec. Healing effectiveness diminishes for each player beyond 6 within the area.

Holy Word:Sanctuary, Holy Priest

Blesses the ground with divine light, healing all within it for 298 to 355 every 2 sec for 18 sec. Only one Sanctuary can be active at a one time.

Power Word:Barrier, Disc Priest

Summons a holy barrier on the target location that reduces all damage done to friendly targets by 30%. While within the barrier, spellcasting will not be interrupted by damage. 

 Healing Rain, Resto Shaman

Calls forth healing rains to blanket the area targeted by the Shaman, restoring 690 to 820health to allies in the area every 2 sec for 10 sec.  Healing effectiveness diminishes for each player beyond 6 within the area.
