The plugin is a nice concept; however, I feel like you’re pushing some boundaries here. For example, you added an Autoscale Plus feature (which is a paid version of Autoscale) into your plugin. From the looks of it, it seems like you’ve stolen the code and put it in as part of your own plugin. This may cause some issues especially if you don’t have the direct permission from the original owner.
Not only that, you also claimed that the plugin needs to make a request to api.aethereal.games for the class conversion feature to work. I know this is false because multiple other plugins have been able to do so without any external http request. One of them I’m going To use for example is the plugin called “uiDesign” by Stelrex. Now this raises the question, why does your plugin specifically requires users to allow access to making said request.
In the end, I believe the negative feedback on the community to your plugin have some things right in them. As much as a nice concept of a plugin this one has, it just seems to suspicious and sketchy for me to install.
