Yeah, like... Why though? Are they just done with MP cards because they think it discourages people from whaling? Asymmetry drives me crazy and this is asymmetrical (and just shitty obviously).
Literally the only reason I can think of is Xmas has just not sold well, so they downsized it's upgrade, and decided Gremory was clearly too strong to be an MP card (Which is honestly fair, girl is strong as shit and has a majority of the best red cards.) and just decided this would be okay.
Which it's not honestly.
It's probably just a comical mess of bad decisions and/or conservation of resources that just happens to screw over the unluckiest color.
Red has majorly benefitted from R/D Haku (Dark board change works with minerva which is really good) and well, Redbei (He's probably a solid top 10 at worst.). And Gremory is a HUGE jump in red lead power. Like, this is still REALLY GOOD.
....but it's stuck in an annual Rem and there's 0 pity for non-iap red players in this rem because xmas sonia is b a d.
Either that, or they wanted to focus on ny round 2 more and the two are far too close together (Your own damn fault there, gungho. Don't screw people over for that one.)
