Really just a post because i don't believe one exists for this specific distro,
Zorin makes running Warcraft 3 very easy, this post also covers modding/maps/custom campaign status and the world editor.
Installation:
Install warcraft 3 as per standard, in my instance i have an old disc and that is what i have used 
To run the game and start playing
Double click on the .exe file in the Warcraft3/x86 titled "Warcraft III.exe" then click
Run Anyway
And it will launch as per standard in the amazing 4:3 aspect ration, there is a common widescreen fix you can apply called "RenderEdge_Widescreen" this appears to work for windows AND linux installations of the game, this is just placed in your Warcraft3 Folder, this fix applies ingame but not in the menu.
Custom Campaigns/Maps
These work as per windows simply drag and drop the files into the respective files these can be downloaded usually from the hive
World Editor
The World Editor for Warcraft 3 is ALOT less stable then the game Warcraft 3 itself on Linux via the windows app support on Zorin is painless and runs great.
The World Editor on the other hand appears to be hard coded to use the default system windows/tab settings which means its style of windows trends towards Zorin and Gnome pretty instantly however,
it can hang quite frequently when loading up the x86 editor is the most stable the x86_64 is to unstable to even minor use.
To get it running
head to the Warcraft III/x86 folder then double click on the .exe file called World Editor.exe and then click Run Anyway
Some patience is then required as it may stop responding however rest assured it is loading, once loaded in you are fully able to access all functionality, i recommend you zoom in where possible to keep the performance manageable.
Triggers, Doodads work fine, mass terrain modification and large brush sizes lead to some noticeable frame drops, but this should not be a surprise.
If you happen to make a map or campaign for warcraft 3 or just enjoy playing it on Zorin let me know, I am toying with the map editor at this stage and happy to talk the world editor with those learning the tools.
