This comes from a guy who not only loves trailblazer (1 of my favorite characters) but also March 7th and consequently Evernight (duh).  
  
  
So, we all know (I hope) RMC is way better than Castorice for a Main DPS Evernight Setup given the Crit Rate buffs and action advance.  
  
The thing is... already know Aha's funny ass is gonna give an amazing design and kit to EMC making it far in a way better than RMC. (When it comes to design it's mostly subjective but genuinely, isn't RMC just normal MC with a pokemon? HMC atleast had an hat which i found really cool and it's probably my fav design of it, but that's probably just me speaking).

Even if RMC somehow ends up being better than EMC it's probably because EMC is very niche and even then the game will shill that niche in 4.X making it basically necessary and the equivalent to HMC in 2.x.  
  
  
I am not saying i don't like Castorice, i certainly find her cool and charming as her own character and i actually have her from summoning on her release, but it's really stupid how i can't make Evernight the focus of the rememberance team specially when March has always been my favorite female character since i started playing.

  
Even Harmony MC i'd love to use in the other sides with Break since he's my favorite path but nooooo, i'm stuck with RMC for my Cas so i can't even use him or else my team lacks consistency (I missed evernight's first banner, only came back 3 weeks ago...).

Then there's also the fact they don't let us use both Hunt and Preservation March which is honestly a bummer considering Preservation March got a skin but isn't as good as hunt March which is also underwhelming on today's meta nowadays...  


All of this to say, Hoyo should seriously make a character's multiple paths viable in 1 character instead of making players have to summon for Castorice or Tribbie, 2 characters some might not like, to have a functional Evernight team.

  
I doubt anyone at Hoyo is on this sub considering many "character mains" sub contains leaks (just like this post here) but man how i wish they were more attentive to this.

They should really let us use more than 1 character path at the same (Kinda Rant Post)
