My guess is that NMM was practicing battle magic for a while before issuing the challenge. His much prep did Celestia have?

Who is to say NMM was unbalanced? Good girls have righteous rages against villains and we don't call them unbalanced. It is only "unbalanced" if you think equal peace with Celestia is an option.

Celestia had a thousand years to study the elements and learn to use them for mind control. All to herself. Back when the sisters shared them there would be no time or incentive for personal study.
Celestia viewed Luna as naturally submissive and obedient until she rebelled so she didn't think to explore this until after. Probably perfecting it on her subjects.
As for how Twily managed it: Celestia was grooming her for years as her apprentice. She probably cast all kinds of secret spells on her so that when she uses the elements this would happen.
As for why she did: personal risk. Why risk death yourself if a unicorn can beat your enemy for you?

I need more stone ponies theory…
Another idea occurred to me. What if the effect of EoH is to harmonize the user with the target by moving them toward each other in power and personality?
This would explain how NMM grew in power. She absorbed Celestina's magic. This is why Celestia could not beat her next time.
This is also why a bunch if weak ponies had to use them. It lowers NMM's power level and moves her personality toward the Mane 6's.
This also explains how the Mane 6 grew in power. They absorbed some of NMM's power and emotions through harmonization. This is how Twilight could become a princess and how Rarity can go Nightmare. How Fluttershy can go Flutter bat. Why Dashy got her rainboom. Why AJ is strongest. Why Pinkie is a reality warmer losing her mind at tea parties.

Celestia could not help her sister because using the EoH on NMM would only impart more of Celestia inside her. That would make her more power hungry.
NMM post-moon is more evil than NMM pre-moon because she absorbed Celestina's evil.
Twily and co using it neutered (fixed indeed) Luna by imparting their subservience (they all worship Celestia) into NMM. Only they could do that because the EoH "harmonize" user with target and make them more alike each other.

I see no evidence we should assume elements were bound to either sister. NMM is the real Luna. EPs 3+ is lobotomied Luna.
Tyrant Celestia is a solid theory. It isn't made up. It is based on her millenium-jailing then contract mind raping someone who wants her job.
I see it wrong to say what the Mane 6 did was "fixing" her.
The word is multifaceted. Do you mean repair? Hurt? Neuter? I bekieve the latter two is what happened.
