you know I was just trolling a bit, I didn't expect people to go crazy like that xD
back to topic: what you said has no relation to the discussion and isn't true either. if chrysalis was weaker than celestia, she wouldn't have defeated her.
it just puts the mightiest pony in equestria in a weird position if she always has to rely on others if some remotely powerful "villain" appears.
don't take it(or me) so seriously, it's a kids show (and I'm a troll) ^^
