Pfft. Well I do admit she does give ponies the love that I need for my hive. So her being in power does aid in my kinds survival too~ Though seeing her reign Equestria does rub me wrong...
You mean she's willing to send others to fight them? The only I times I can think of when she actually fought herself were sending her sister to the moon, trapping me in stone (with the aid of said sister), and trying to fight Chrysalis. Everything else she farmed out.
Yeah... She has gotten weaker over the ages and she knows it, especially with the Elements no long in her control.
