Well yeah, it's that too. Probably better if we just get a new letter. Preferably a consonant. Vowels are NOT good for these 4 letter names. I was thinking about it, and none of the three teams we see in the original RWBY have vowels (unless you count y I guess.) JNPR (juniper), CRDL (cardinal), RWBY (ruby). I realized what made them work is that the vowels are all assumed, which makes it way easier.
