I'm more on the defensive type. If I ever go into a fight head on, I must have some sort of gear advantage over them. If not, I might run until I get some sort of advantage. For instance, if I had maybe, full chain and an iron chestplate. My enemy has an iron chestplate and boots, along with chain pants, and a chain helmet. I would then run, and try to get them with whatever strategy I can come up with. I most commonly do quick flint and steels to try and light them up. If that fails I may keep running. Or trying to get them in a chokepoint such as a doorway. I also like to do a quick 180, then shoot them with a bow. This sometimes works, especially if they're in the air when you hit them.
