War-toise (Tortoise)

Play on words aside, today's idea consists of a new mobile attack unit. The War-Toise would be a slow moving, Dark Elixir altered Tortoise with a slow firing, cannon on its back. The tortoise's firepower would have a reduced range compared to the defense counterpart to compensate for the ranged capabilities. I know there have been suggestions as to mounted defense on a Bear or (Elephant i think?) mine would be different in its weaknesses and strengths.

Maybe if people like the idea, this troop could target a section of wall with its cannon to open up compartments better then WB having to run through the base avoiding splash damage or mass troops converging on one wall. This would not replace the WB in the fact that they do 1k plus damage at level 4-6.
