I love Yordles. We need mordles.
Jokes aside, the fey creatures aspect is really interesting. Yordles seem to be something that's kind of the antithesis to what demons have been built up as, if I'm reading into things right. The "Patron Yordle" thing they've been doing is also an interesting aspect of their existence and I hope they come up with one for the Shadow Isles soon.
Bandle City is one of my favorite factions in the game and I absolutely cannot wait to get more lore on it. I do hope they keep the Mothership from the old lore. I know GreenLore said the military aesthetic of some yordles clashes with what they have been presented as, but to me that contrast only makes them all the more interesting. Why DO the Bandle Gunners exist? How did these fey-like creatures develop tech equal to if not surpassing Piltover? I'm very eager to learn.
