There are many different MCEdit alternatives that can be used for any version of the game, however, the one that I am using tends to work best with the latest patches. If you are having problems with World of Warcraft's combat, then MCEdit has been known to cure the problem to an extent. It's a great program that enables any player to make their character as cool looking as possible. Below I will give a quick summary of what MCEdit is and how it can be used.
MCEdit is a program which modifies game files to make them reflect real world specifications. It can be used to create enchanted chests, readable books which players can pick up, enchanted weapons, enchanting table, dye with click, enchantment scroll and many other things. Mcedit 2.0 is in alpha stage and all the functionality features have yet to be fully completed.
To make mobs with swords and armour you first need to download the MCEdit pack called generate geared mobs. To get the pack go to the MCEdit download page and follow the simple instructions on how to install the pack. The program is then ready to be used. Just open the MCEdit interface by clicking on the "mxedit" icon, select "configure" tab and follow the instructions. It's very basic at the moment but the team are always working on making it more useful and adding new features!
