I don't visit r/XenobladeChronicles much anymore but every time I do, there is a Rex Defense Squad post near the top of the "Hot" page.
Me neither as well, despite my reason is different, I just don't visit Reddit often unless I want need some help, like finding certain materials and other stuff...
And yeah...I don't like Rex that much compare to Shulk and Addam...not that I agreed with the post in general but it's not like I am bumped by it, everyone has their opinions and this is something that I don't consider something to be out of Reddit... one thing I have to say though... what happen to the Xenoblade Reddit site? I mean the aesthetic, it was cool and have the Xenoblade background with the Aegis as your mouse key but now it has changed to a generic Reddit thread...
Also, labeling others isn't getting you anywhere... if a user want to "defend" a character or anything just let them do it, if you have your own rebuttal then just do it too instead of outright labeling others. To be fair, you did give your own opinion and besides of saying Rex and Pyra/Mythra's relationship is a force romance (When there wasn't any actual romance between them at all), which I agreed with you there that Nia share a better relationship with Rex, that's what makes her awesome but it would be nice if the game gives us a better flashback on her past.
Off topic... My Valkyria Chronicles 4 arrived like early... I thought it would arrive around October 24 but it is here on my hands... thats Amazon Global Shipping for you.
