New Troop: Freezer (Name not final)

New Troop Suggestion: Freezer

Damage = 0

Attack range = same as the archer's
Attack speed = slow (maybe the same as the dragon's)
Target: any structure ( My first idea here is that his favorite will be defense buildings but I think its kind of imbalance)
Splash dmge: NO
Movement Speed: same as the Barbarian's
Description:

Every attack will make the target frozen for a span of time ( 0.5 / 1 /1.5 seconds ???? Im not sure if what value is balanced)

If the freezer attacks a non-defensive building it will be useless... I love the idea but you have to decide its housing space, cost, training time and HP. I'm afraid it could be OP if 5 freezer freeze a defense one after the other while giants destroy it.

Oh I can't think of any details yet. Though its just a concept. :D Would be nice if they make it official.
