One of Mythra's alts has white tights, which looks so much better than the ugly black ones her Spirit and her normal costume have - why didn't they go with white from the very start? That was stupid.
Mythra's meant to be kinda angelic in appearance, and she's the main Light Blade, so dark colours don't work well on her at all. White tights are great, compared to black - though I still prefer her uncensored appearance.
Additionally, what's this nonsense about "Pyra specialising in power"? As is stated in Chapter 2 of XC2, and expanded upon in Chapter 4, her power is a mere "trickle" seeping through the seal - nothing, compared to Mythra. Heck, Pyra was created to limit the power available, after Mythra was traumatised at the end of Torna: The Golden Country.
The only ways Pyra's stronger than Mythra is in Blade Combos, thanks to one of Pyra's skills augmenting Blade Combo damage by 72% max, and having a crit-buffing skill - apart from that, Mythra's by far the more powerful sister.
So yeah, that makes no sense whatsoever.
Lastly...apparently MONOLITHSOFT was working on both this fantastic game and on the mediocre Breath of the Wild at the same time, and despite this split attention, XC2 turned out to be an outstanding game - but imagine the possibilities had they not been forced to split resources on that other trash. They could've had better tutorials in XC2, or added a Collectopedia, or fixed the handful of typos within the script, or made some skill descriptions more helpful, or something.
What a waste of resources, working on the repulsive BotW.
