He isn't really enlightened. Just sort of. To the point he can pop around and spread words of nonsense and wisdom. It wouldn't dramatically steer the direction of the story. :) I put his race as an enlightened being more because that is what he considers himself and because he is unlikely to fit into any category as he is technically alien. 
Why is it unbalanced? Maybe hundreds was a high estimation, but he moves around very quickly in battle so he would use lots of portals.
He has no enhanced physique, so he wouldn't be taking on armies or anything. 
His ability to move between dimensions is rooted in his character because he is a nomad from a magical world. He is on Earth
to help protect humanity, but that means helping it help itself. Rather than opening pan dimensional portals for everyone which would affect the storyline negatively, his purpose is to support other characters, to guide.. blah dee blah. 

I hope that helped.
