but i agree. there would have been better choices but i knew immediately who he was. (it seems nearly to no one watched hercules series 
)
about Orpheus i agree but maybe a bit too strong with his aura. I also agree with Icarus.
King Midas i was first disappointed till i knew he could make units into cool gold statues. but this happens way too rare. but i like the sword and the beard he wields. 
glad they tried to buff him and make his gold special more frequent.
