To be fair, the original anime also used "Moon Healing Escalation" as an offensive attack, so that's nothing new unfortunately. But the Sailor Planet Attack thing...
The problem with Crystal (season 1 in particular) wasn't that they changed stuff, it's that they didn't think through any of the changes they made. There were changes that worked (Usagi's dream at the start of Act 1, the girls having a flash of memory upon their first meetings with Usagi, even keeping Jadeite alive so that we could get all Four Kings together in Act 4 I thought was neat), changes that were arbitrary/a bit of a letdown (leaving Moon Twilight Flash unnamed, not including Rei's grandfather), and changes that were a disaster because there was no room in a 1:1 adaptation to develop them (SenxShi pairings) or because they created plot holes (Usagi not being a victim of the mass brainwashing this episode, the Four Kings being destroyed by Metallia in Act...12? 13? I forget which - yet Mamoru was still spared from being killed because he had their stones in his pocket???) or because they were the absolute most embarrassing thing I have ever witnessed in all my days (Usagi has to stab Beryl's necklace to defeat her now? Really? Are you actually serious right now? How much crack are you doing?). It was all just so amateurish. They refused to think through how their changes would affect the story or if there was even time for their changes to be implemented. Like, I'd love to see a version of the Dark Kingdom arc that incorporates the Sailor V manga's story/characters, but it would make zero sense to try that in a 1:1 adaptation. The idea of SenxShi pairings can work (see: La Reconquista), but not in a 1:1 adaptation of a work that didn't include such an inherently major storyline in the first place.
Plotting... Rational thinking... These things aren't difficult, Toei, I promise.
