I think they adjusted dragons in response to the complaints.
For the past week or so I have noticed a lot of odd movements by drags that go beyond what they did before. I think we all knew their AI had been programmed to be 'stupid' in that it would pick useless targets (I.E. resources, cc, ground def) over useful ones (air def, TH, towers). I think it used to also not be based on closest target, if there was a bad choice less than a couple squares (estimate) further than a good choice it would travel the little bit further for the bad choice.
What I have seen now is some ridiculous distances traveled to hit a bad choice. A couple times going right past a good choice to hit a bad choice on the far side of it. I think they moved that range from 1-2 squares (estimate) out to 4-5 (still estimated).
This is not a beef, I have seen dragons from opponents do this too (I have been both hurt and benefitted by this dragon behavior) so the playing field does remain level. I am just stating an observation I made. I wouldn't want to debate whether it is good or bad, just say that I think it is happening and that we should factor it into our strategies going forward.
I am posting this in the ideas forum because this is where all the complaints and demands they do something about the dragon raids were getting posted. I think they heard and responded to you guys.
