I remember Arjuna from the book Bhagavad Gita, he is the warrior who choice to hear Krishna. I also see in Wikipédia he is son of Indra.Leaving that, I don't think including deities like Indra, Agni,Mitra would create any problem. Also there are many outrage free Mahabharat heroes like Arjuna,Bheem.

I'm very cool with Arjuna be in the game, at least will well represent the Hindu culture. Because the last Heroes&Legends don't have any Indian.
