What also makes them weaker is that they are tied to a single sphere of influence. Now heres a question folks how ya gonna handle Chrysalis. After all she did take down Celestia (if you ignor the fact the bug was a complete dumb dumb in the end) so that proves there are more powerful things out there than an alicorn. So I present a challenge make something stronger than an alicorn.

I always viewed that fight in the context that Celestia was holding back due to all the innocent ponies that were around them while the fight was taking place. Roasting her loyal and loving ponies by accident seems like the kind of thing that would haunt her.
