New Dark Troop :D

Hello I am making a idea for the next dark troop!

Name of Troop: Dark Healer
Training Cost (in Elixir or DE): 400 DE
Training Time: 20 Minutes
Housing Space: 14
Heal per second: 70 (At Level 1)
Hit Points: 1000
Movement Speed: 14
Description: This dark creature lives to heal all of her fellow troops. She will heal even dragons. Be sure to keep this creature away from defending dark troops.

This will be essentially a buffed healer. But, this healer will all troops, even air ones. But, to balance this buff, she gets extra damage from Dark Troops.

Please leave suggestions!

Read the stickies! In there if you go to ruled out you shall see you cant alter a healer to heal air units! Plus, this has been said a billion times already!
