New troop: tank

Now, we already have the golem; but I think it is a bit too OP for normal players; so I thought of this troop whose only purpose is to shield allied troops from upcoming direct attacks (ex. Mage tower, cannon, X-bows...), non "sky-diving" attacks like mortars.

Name: Shielder
Cost: 1.000 DE or 20.000 E
DBarracks lvl: 6 or Barracks lvl 11
In the battlefield the Shielder acts like a healer, but he puts on shields that protect allied troops, like these

or just an area defense; it attacks every 2-3 seconds (too op if it attacks every second)

maybe it should be more pricy? Please answer if you read this post plzzzzzzzzzzzzz :o:o:o:o:o:o:o:o
