Great ideas for healers

you nerfed Queen/healers combination, still there are people using it well.
Also , healer is unefficent with others.
What im suggestings are nerf queen/healers stragety, and buff healer itself.

First. I have 2 options How to nerf healer.

A. increase healers housing place to 15~17 from 14.But buff low lv healer.
this change will be affect queen/healer stragety critically becuz if you take more healers other units will be decreased more than now.But this chage will also affect low lv users. so we need to buff low lv healer to cover it.

OR

B.Make airbomb detect healer as favorite taget(x5).
2 air bombs will excute healers at once. if attakcers want to prevent it. they should take one heal spell for healers. and it will be huge nerf for queen/healer stragety

How to Cover these nerf?
Increase healers max level.(lv5 or 6)

Please share your thoughts. and I hope you like it.
