First born armor ASAP

Add First Born marine armor as soon as possible please. Primaris armor is alright but it is simply too bland. 

Mk 3 iron armor, Mk 4 maximus, Mk 6 Corvus, Mk V heresy, Mk 7 and Mk 8. All look better than primaris, throw in thunder warrior armor in there. 

I don't want anyone saying how they can't add it because first born would be ''smaller'' when we literally have first born chaos marines that we play as in pvp, also even if that was the case which it is not, because marines vary in size, they can simply be made the same size as the primaris and chaos marines for balancing sake. 

Focus do not make the same mistakes that 343 did with halo infinite and dripfeed us content, It's a no brainer you will add the opening mission firstborn deathwatch armor sooner or later but please don't drip feed, or wait to release the actual good looking armor when the games lifespan is close to finishing.
