Self mitigated damage, to my understanding, is all damage absorbed by resists (be they armor/mr or stuff like Garen W/Amumu E) and shields on yourself. Since you got a BT relatively early, all damage that hits that is registered as self mitigated, because it's damage shielded on yourself, so it goes in the "tankiness" selfish stat rather than in Ally Shielding, which is supposed to be an enchanter stat for measuring how much they contributed with their more selfless focused buttons.
Hey Mike! i've following for a while, loved your videos, your energy and humor. (as a balding 36yo i relate a lot with you lol) Just wanted to drop a question: do you intentionally not show runes picked? would love to see them so i can understand viable builds anyways, love the content, specially this new 'nameless' series (not using the champ after a loss)
Maybe it has been a while since I've seen you play her, but your Fiora is super clean, dude. She's so unlike any champs I typically play, but now I've got the itch. Lolol GGWP, brother.
Side note: if the jury is still out on the series title, I like the idea of calling it the "Battle Royale Challenge". Battle Royale is generally used to describe a contest where all participants compete until the last man standing is declared the winner. I feel it both encapsulates and offers a touch of swagger to the series. 😋💕
