Ok there are some things wrong with your tips:
-Block is useful. Predict the rate of a bow and you can half the damage every time.
-With higher ground, the player below can attack easier as their attack range is extended
-For jump attacks, it can really slow down your movement except for Jump sprinting and reduces DPS because you only attack while you move down, while when your standing still, you can spam all hell
- Just because the person has the better sword and armor doesn't mean that you can't win. Use the terrain as an advantage. If it's up in a mountain, try to knock em off with a sprint. Also, when near a ravine, knock him in there and escape.
