Singed passiv

HI ! As a main, i'm looking for a new passive to replace the current one (+MANA => +HP), because i think it is not the best passive that singed can have. This is why i worked on a new passive that can be interesting :

Current passive :

Empowered Bulwark

Singed gains bonus health equal to 25% of his maximum mana.

New passive :

Boosted Body When Singed is moving, he obtains bonuses of statistics over time. (level 1/6/11/16) Singed loses his additional stats and his bulwark special effect, if he's rooted, stunned or bumped or if he's not moving for 4 seconds.

When Singed is slowed, the passive will decrease, loosing 25% per seconds of the accumulated effect until 100% of the effect if the slow duration is more than 4 seconds.

Exemple :

Boosted Body _Level 1 : _ (+1 Armor) / sec (Max = 15 armor over 15 seconds) (+1 Magic Resist) / sec (Max = 15 Magic Resist over 15 seconds) (+1 MoveSpeed) / sec (Max = 15 MoveSpeed over 15 seconds) After 15 seconds in movement, Singed's Bulwark blocks 5 % of the entering damages. (Does not affect minions or monsters)

_Level 6 : _ (+1,67 Armor) / sec (Max = 25 armor over 15 seconds) (+1,67 Magic Resist) / sec (Max = 25 Magic Resist over 15 seconds) (+1.67 MoveSpeed) / sec (Max = 25 MoveSpeed over 15 seconds) After 15 seconds in movement, Singed's Bulwark blocks 7,5 % of the entering damages. (Does not affect minions or monsters)

Level 11 : (+2,33 Armor) / sec (Max = 35 armor over 15 seconds) (+2,33 Magic Resist) / sec (Max = 35 Magic Resist over 15 seconds) (+2,33 MoveSpeed) / sec (Max = 35 MoveSpeed over 15 seconds) After 15 seconds in movement, Singed's Bulwark blocks 10 % of the entering damages. (Does not affect minions or monsters)

Level 16 : (+3 Armor) / sec (Max = 45 armor over 15 seconds) (+3 Magic Resist) / sec (Max = 45 Magic Resist over 15 seconds) (+3 MoveSpeed) / sec (Max = 45 MoveSpeed over 15 seconds) After 15 seconds in movement, Singed's Bulwark blocks 12,5 % of the entering damages. (Does not affect minions or monsters)

I also modified slightly Singed's ultimate.

Insanity Potion COST: 150 MANA COOLDOWN: 100

Passive : When this spell is on, Singed loses his additional stats and bulwark special effect and can't stack it for the entire duration of this ultimate.

Active : Singed drinks a potent brew of chemicals, granting himself 40/60/80 ability power, bonus armor, magic resistance, movement speed, health regeneration and mana regeneration for 25 seconds.
