Shield Rework

*Disclaimer: This post will contain references to my other combat ideas. I will link them in the appropriate location as soon as possible

One of the major problems with 1.9 pvp is the slow paced pvp caused by shields. I suggest remedying this by introducing a shield strength system. 

A shield will have a strength bar, which is capped at 100 and refills by 20 every second. When the strength bar hits 0, the shield will be disabled for 5 seconds. The strength of a shield will be decreased by hits:

Axe: 25 per hit

Spear: 15 per hit https://feedback.minecraft.net/hc/en-us/community/posts/360076433471-New-Weapon-Spear 

Sword: 10 per hit

Dagger: 5 per hit https://feedback.minecraft.net/hc/en-us/community/posts/360076576492-New-Weapon-Dagger 

The strength loss will also be multiplied by the following factors: 

Attacker is sprinting - +300%

Per level of knockback on weapon - +50%

This will mean that the axe is still the best counter to the shield, however the shield does not all but invalidate other weapons.
