Nice idea, but I think 300 levels is far too long, I would say 150 at the very most. Also, the loot for Campaign level 50 is 800k gold and elixir, at level 300, the loot would be insane. Another cool idea would be to see X-Bows and Inferno Towers in later levels, and also dark elixir to be stolen instead of just gold/elixir. :D
