Uh, is the part about influencing drops true?

Well, I never heard of it before, but either way, blues?

Remember the Mida multi-tool pointing to chests? This is the same level of sloppy quality speculation. Not only do these not influence anything, but iirc, some Bungle guy confirmed that they just look cool.

I've been wearing Shield of Mythics since Day 1 (except for Iron Banner) and I get nuthin'.

This would be so incredibly awesome if it did, but then, I'd feel obligated to always wear & share this. I would miss out on other cool emblems I have such as "The Inner Chamber".

There was a lot of speculation early on about the emblems sold by the Speaker, but that was shut down pretty quickly:

Dang. Instead of "Kermit sucks," I was hoping the thought process would be "Kermit sucks, but he's got that emblem buff!"

I've kind of given up on it by this point :(
