Come now, Hades is powerful, I agree. but I wouldn't go as far as to say "Far too Powerful". First of all, we have not seen much more power from him than we have from Rumple, Emma, Cora, Merlin, etc. Plus (unless something changes), his power does have limits when he is topside, to the point that he is probably in the same power range as the rest of the magicians.

And if you're worried about power, what about Rumple 2.0, Emma, Zelena, or Regina?

Of course, they have enough trouble getting main cast in stories (Robin, Will, Belle, Neal), so I don't see him becoming a regular. So maybe you're right. one or 2 episodes per season (probably depends on where they leave his relationship with Zelena when the current arc completes).
