[Complete] Boot Overhaul (Simplified)

I'll get straight to it, boots losing the enchantment options was a hard hit, and the resulting boot options we currently have are a shell of their past potential. I'm not looking for suggestions, if you have your own please make your own thread if you feel similarly. So here are my personal ideas for all around improvements to the boot upgrades. All boots upgrades will have a base movement speed bonus of 50 and cost 1,500g a piece.

(Boots of Speed) Unique Passive - Enhanced Movement: +25 Movement Speed.

(Boots of Swiftness) Unique Passive - Enhanced Movement: +50 Movement Speed +5% Movement Speed. Unique Passive - Swiftness: -25% Movement Slowing effects.

(Boots of Mobility) Unique Passive - Enhanced Movement: +75 Movement Speed Unique Passive - Captain: Grants 10% Movement Speed to ally champions within 500 units.

(Berserker's Grieves) Unique Passive - Enhanced Movement: +50 Movement Speed. Unique Passive - Furor: Basic attacks on enemy champions grant +10% Attack Speed and 5% Movement Speed, stacking up to three times, for three to nine seconds.

(Ninja Tabi) Unique Passive - Enhanced Movement: +50 Movement Speed. Unique Passive - Ninjutsu: 5% Damage Reduction, +10% to the rang of Dashes and Blinks. +25 Armor

(Mercury's Treads) Unique Passive - Enhanced Movement: +50 Movement Speed. Unique Passive - Mercury's Step: Reduces the duration of stuns, roots, taunts, charms, fears, silences, blinds, polymorphs, immobilizes, knock backs, and pulls by 25%. +25 Magic Resist

(Sorcerer's Shoes) Unique Passive - Enhanced Movement: +50 Movement Speed. Unique Passive - Sorcery: Dealing magic damage to enemy champions grants +5 Magic Penetration stacking up to five times for ten seconds.

(Ionian Boots of Lucidity) Unique Passive - Enhanced Movement: +50 Movement Speed. Unique Passive - Distortion: Your Cooldown Reduction cap is increased by 5%, +5% Cooldown Reduction, Reduces the Cooldown of Exhaust, Ghost and Flash and Teleport.

Notes:

Mercury's Treads passive would stack with Tenacity, but would not grant slow reduction, allowing for more diversity from boots of swiftness.

Ninja Tabi new passive would reduce damage from spells, though it would be significantly less damage reduction it would also grant better utility for, you know Ninjas.

Boots of Mobility given less potential but more solid Movement Speed takes the anti-fun from getting a random poke or mini at the start of a gank.

Will be on later to answer questions and explain more.
