Spears, shields, spear balance ideas

• Right click with a shield in the left hand works both on the shield and the spear at the same time. It's more realistic, more comfortable in survival and not a gamechanger in PvP (compared to what we already have with spears)
• The amount of durability spent when hitting with a charged attack depends on the damage dealt (imo it's fine if a spear breaks after attack)
• Hitting a shield with a charged attack drains more spear's durability and stops the attack (maybe the spear gains a cooldown).
• To hit an entity with a charge attack your cursor has to be on its hitbox.

This is my vision of the spear, critique and discussion are welcome.
