Nature's swiftness + Chain Heal (which heals a lot)

I guess that is one of the answers, though healing wave would heal for more.

Reason for this is druid can use feral charge wich would prevent healing for 4 seconds.

If you do not have NS then the answer is to drop a grounding totem first as this will absorb feral charge.

Your turn to ask a question Bananaz. :)
