Currently the list of available mods for the WoWs version is directly included in the modinstaller itself.
Because of that you need to create and upload a new version of the installer everytime you want to add or remove a mod to it.
A better idea would be to create a list (xml or json or whatever you prefer) and just download that list on loading the Installer.
That way you can add / update / remove mods on the fly without rolling out a new version of your installer.
Pros:
- Easier adding / updating / removing of mods
- You don't need to download the whole installer again if there's a change in the modlist
Cons:
- More serverload (due to the modlist request)
