Always jumping when fighting.

If what you're saying is that jumping causes criticals, I believe you're mistaken. A critical melee is caused by falling, not jumping. For proof, this is from the Minecraft wiki:

That is exactly what I'm talking about. When you jump, once you reach the height of your jump, your character begins "falling", enabling crits to happen, so indirectly, jumping does cause crits.

I'm going to say two things that have already been said

Jumping and strafing is good in most cases, as long as you're not on a mountain or somewhere where you could take fall damage.

If what you're saying is that jumping causes criticals, I believe you're mistaken. A critical melee is caused by falling, not jumping. For proof, this is from the Minecraft wiki:

What happens after you press the key designated to "Jump"? Your player rises then descents, you can get criticals when you're player is descending back to ground.

Don't jump off a cliff or you will go splat :3
