Dark "SLIME BALL" Troop Idea

I've got a new idea for a Dark Elixir troop! It world be a slime monster that will attack any building. It attacks by chomping up the buildings dealing half the attack power of a P.E.K.K.A. (120). And as much HP as a Hog Rider (270), but this troop heals itself up (Just because it absorbs the shots it takes). Regen rate will be 7 HP/s. When this troop is killed, it will divide itself into 3 mini Slime Balls (NO EXPLOSION DAMAGE) which will have 1/3 of the stats for each Mini Slime Ball. Here are the stats for Level 1 only.
Stats:
HP - 270
DP/s - 120
Regen rate - 7 HP/s
Movement Speed - 16
Training time - 40 min.
Dark Elixir cost - 150 DE
Reasearch cost - 32,500
Mini Slime Ball Stats:
HP - 90
DP/s - 40
*No Regen
Tell me what you guys think! Too expensive? Too weak or strong?
