I can't help but imagine these new names might be inspired by someone working on their RDR2 fishing trophies.
Just my 2c, but this seems like one of those 'fix what ain't broken' things.
The names Claymore & Caliburn were there to help clarify that Gaians are stereo-typically the Scottish of Disco.
Sure, Gaian players never really play up the scotish thing, like the Mollys do the Irish thing, but maintaining the original nationality stereotype is better imho.
Please, don't take away their kilts next, we may not like what we see.
