Air Defenses ridicuosly powerful in the game?

Does anyone feel that in the course of last few updates Air defense (air bombs, seeking air mines and quantity of air defense buildings) gotten ridiculous? I recently tried all dragon army, and I got my ♥♥♥ handed to me. Let me quote Clash of clans Wiki about dragons: "The first person to have reached over 4000 trophies (Jorge Yao) used to use an all-Dragon army. He used 4 Lightning spells as support, one to take out clan castle troops and the rest to destroy an air defense."
Do you think Jeorge Yao could climb on to the top of rankings, after all the recent updates to air defense? "...He used rest to take out air defense" Which one?

He did this when there was one less AD in the game. Now the golem, pekka, wizard strategy is the most effective for these top players.
