These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Blaz Blue Chrono Phantasma
Author's Saving Throw: Continuing the CS entry, ASW furthered their efforts by making Litchi look obviously not very pleased with working with Hazama/NOL and her ending involves her finally realizing how foolish her actions are. To top it off, ASW then tried pulling this with the NOL in general so they don't look like an always-evil empire thanks to the addition of Kagura Mutsuki. Head of the biggest and most powerful Duodecim family and a Colonel within the NOL, he's still an actually cool dude who'd shelter Noel and Makoto and chat with them with a smile even if they're public criminals.
On a more serious note, while the return of Mu-12 was quite well-received, people are taking the story explanation for her return with mountainous piles of salt due to extensive Mary Sue implications. As time wore on, the salt eroded away, and the resulting development was welcomed with open arms.
The 3 new characters that came out of nowhere instead of putting in Jubei and Kokonoe, the characters people wanted most.
That being said, there is always the possibility of console-exclusive characters and additional DLC for the console port(s), as was the case for Continuum Shift with Mu and Makoto, Valkenhayn, and Platinum, respectively. Mori has also stated that the boss of Chronophantasma will be something to look forward to, although fan speculation concludes that the boss will either be Imperator Sayanote which has been given a hint or two by Mori's statement that Saya might appear in the home version instead of the arcade release, as well as Yukana (Saya's seiyuu) revealing during BlazBlue Radio Wide's "Riot" special that Mori told her to deny Saya's playability when asked or Phantom (two other characters most fans would like to see playable, albeit not to the extent of the aforementioned Jubei and Kokonoe).
And now it seems the remixed soundtrack, of all things, is getting hit with this. People either love the way the tunes are more energetic and dynamic, or hate it on the basis that it sounds too "generic" or certain songs have portions that seemingly do not fit the character.
Azrael's appearance and combat style have been reasonably well-received, especially in the West. That he steamrolls Valkenhayn, Tager and Jin in Arcade mode all on Enchant Dragnov Lv1., gives Rachel trouble, and forces Ragna to unleash the Azure Grimoire by elevating to Lv2 ... not so much. Story Mode may alleviate this, but the subject is touchy territory until then due to lack of information.
While newcomer Kagura has been well-received, Terumi being his own character separate from Hazama has seen mixed reactions, especially since his inclusion over Kokonoe has trolled fans from beyond the fourth wall.
Never mind that he's been confirmed as a pre-order DLC character before the console version has even been released. We all know how well something like that goes over in this day and age of gaming.
Westerners Love Azrael: The enthusiasm towards Azrael seems to be less concentrated in Japan. A case of Values Dissonance because, like Tager, Westerners value manliness more than Japan. As well as him being a manly fight-happy psycho gives them the vibes of a Western favorite of Bleach: Zaraki Kenpachi. Naturally, in the home region (Japan), the most welcomed newcomer is AmaneNishiki.
Tier Induced Scrappy: Bullet is getting lots of flames regarding playing as an "easy-mode" character, but one of her aerial attacks bypasses invincibility frames. Given invincibility frames are meant to be used tactically to dodge otherwise noisome attacks or get into range, this only makes things worse for her from a popularity standpoint. Although the real reason could just be that out of all the new characters, she's the one that's used the most.
Azrael once had an infinite, which would have given him this status had it not been patched shortly after (read: within the same week) it was discovered, averting this.
