horrible idea with dragon form taking out ground units, why? one easy common sense answer: OP
what i rather want to see is blinking red unit on the radar to indicate moving ground unit so i won't land in an ambush like the Stone Fortress lol.
Another thing i wanna add is Dragon form should strike panic around those i fly over. Reducing their dmg and defense for 15 sec instead farming them with ridiculously op air strike.
I like dragon form for one reason and that's to travel.
