As some know, riot is changing 'offensive to defensive' free stats passives and there's somethings i think need changes, but here is my ideas.

AsheSquare Ashe: Focus Marksmanship: Every time Ashe makes a basic attack, she gains 3/4/5/6/7% critical strike chance, which reset when ashe gets a crit.

EvelynnSquare Evelynn: Determined Killer Determined Killer: Evelynn's spells shred armor and her basic attacks shred magic resistance.

KatarinaSquare Katarina: Voracity Voracity: After casting 6 spells Katarina's next spell will instantly be off cooldown.

UdyrSquare Udyr: Monkey's Agility Monkey's Agility: Every time Udyr changes stance he gains 10% attack speed, additionally upon reaching max stacks Udyr ignores unit collision. (stacks up to 3 times)

VladimirSquare Vladimir: Crimson Pact Crimson Pact: Vladimir gains .5% spell vamp for each % health missing capping when vladimir is at/below 20% health.

XerathSquare Xerath: Ascended Form Arcane Power: Xerath deals an additional 1% damage for every 40 units between him and his target.
