Currently, League of Legends functionally has two sets of critical strike mythic items: Kraken / Galeforce / Shieldbow and Infinity Edge / Quickblades / Rageblade.

We’ve got a big update to crit itemization with the hope of creating a much more open ecosystem of crit items players are excited to buy. E - MOUNTING DREAD CRIT THRESHOLD: 15-65% target max health, scaling with crit chance ⇒ 25-75% target max health, scaling with crit chance.W - SPIRIT CLEAVE COOLDOWN: 16~6 seconds, scaling with bonus attack speed ⇒ 14~6 seconds, scaling with bonus attack speed.PASSIVE - WAY OF THE WANDERER SHIELD: 100-575 ⇒ 125-600.

Critically (heh), they don't have direct replacements to shift to. The wind bros lost a lot of survivability with Shieldbow's downshift from Mythic to Legendary, while Kindred lost a lot of damage with Kraken Slayer's. While we're planning on comprehensive balance followup in 13.11, we're giving some quick buffs to the biggest losers of 13.10's item changes now.
