Yes, I searched, no - I couldn't find anything.
Someone who is TH8 or higher, could you please tell me if it's worth upgrading the dragon past level 2? I see that the damage and health are not scaling very well with the increase in cost. 30k is still "reasonable", because with 10 of them you can take down a base that has 300k elixir, but I rarely find bases with more.
