Ysera's Gift
100 yd range
Requires Druid
Requires level 30
Heals you for 4% of your maximum health every 5 sec. If you are at full health, a random nearby injured ally will be healed instead.
That's how it heals the raid. I'm inclined to agree with the YG crowd. It's free, constant healing and it's relatively smart with 3x the throughput. The Druid toolkit is sufficient enough to do anything that CW might help you with.
