Yo man,
I love the guide, very original. I don't have much feedback except these 2 points:

1. Perhaps you could add detail to the matchups. Building Lethality/Crit could be different from the regular Eclipse or Titanic Hydra build, so the matchups may differ based on it. E.g. Sion (since you build Lord Doms), Singed (harder to stack Hubris) or Irelia (has a built-in anti-burst ability).
2. Make the chapters more readable by using colors, formatting and (if you're feeling fancy) tables. There is some great information in there, but it's very hard to read when everything is plain white.

And a question for my own interest, why do you pick Transcendence and Gathering Storm over Sudden Impact and Eyeball Collection?

Look fantastic man, going to try this soon!
