Please advise

I want to play world of Warcraft 3: Frozen Throne but mainly just for the world editor feature where you can design and customize your own maps and characters and stuff. I need to know exactly what I need to do in order to play this, such as, what exactly do i have to buy and/or download, and from what site or service or whatever? I am also looking into buying a new laptop or PC so any advice on what would be the best PC brand or design to use as well as best required operating system in order to atleast run this games minimal functions, would be greatly appreciated. I may or may not check this site frequently for replies so please also feel free to email me at savemysoul7x@gmail.com with any information or advice. I am also looking for other proficient editors and designers who know a good bit about the world editor features and how to use them to collaborate with to design a custom map/ world. If anyone is interested or willing and able to assist with this, again, please let me know either on here or at the provided email address above. Thanks in advance.

Can you be more specific about what you mean by “Warcraft III: Frozen Throne” ? At this point the only really officially sanctioned way to play “Warcraft III: Frozen Throne” is to play Reforged, which has replaced Frozen Throne and is meant to be a superset of its functionality.

In practice, however, there are still some basic World Editor functions like editing a unit Ability to require multiple techtree items that have never fully worked properly on Reforged. So, players who want that kind of stability probably use their backups of Frozen Throne from before Reforged.
