Ever wonder why you're getting tank augs on an ADC, or mage augs on yasuo? I think I figured out why

I've had many a game where I thought "why am I rolling Tap Dancer and Scopier Weapons on Ornn?" Well it seems like your augment rolls are based on the champion you get when you first enter a lobby. If you swap it out, the augments don't seem to realise that, and so when I get Trundle and swap him out for Lucian, I get the Heartsteel augment and other tank/bruiser ones
