Minecraft Dungeons better movement/combat

Minecraft Dungeons should have better movement/combat. For instance you should have a designated sprint button which allows you to sprint for a short amount of time before going into a cooldown (kinda like the roll). For combat they should add a heavy attack for melee weapons, for instance if you hold down the attack button instead of swinging, your character would charge the weapon up, this would deal extra damage to mobs. Finally SHIELDS we all want them, if they were added they would go in your bow slot. Shields would make the character a tiny bit slower and would add a couple of seconds to your roll/sprint cooldown but they would also be able to block incoming projectiles like arrows ect. Shields would not be able to block magic but you could enchant them with enchantments like shield boom (when shield is attacked an explosion will fill the area) anyway the reason why all these things would be great additions is because it would make the game feel more fleshed out. The combat would feel more complex instead of just the mindless button mash we have now and the extra movement and addition of shields would help diverse the different builds that we could make. Also if you added this it would open up to the possibility’s of being able to challenge friends for items/emeralds where you could challenge a friend and 1v1 them putting your most valuable gear/currency on the line. Please add this. I don’t care how long it takes just please it would make the game 100 percent better.
