I assume it's all insecurity. Their ship is weak, so they are compelled to keep pushing it, lest even one person go "y'know, this other ship is pretty good too". Once that happens, the whole house of cards comes crashing down.
RubyMaru got overtook by YohaMaru, which got overtook by YoshikoRiko after season 2.
Now the only Ruby ship that basically exists now is RubyLeah (Which not gonna lie, is adorable) and the ever so incestuous DiaRuby
My reaction to this is both 'What the fuck did I just read?' and 'This is fucking hilarious'.
Where's the 'What the fuck am I reading?' tag when you need it?
I like to think this is before the Talon family all got dumped and Tracer went with Emily, Mercy went with Pharah, and D.Va went with Brigitte. Or better yet polyamory?
