The idea is excellent; servers that use this type of system usually require a lot of scripts and other plugins to do so. It's a good idea for balancing network load. You've created an all-in-one, brilliant idea. Make it Velocity-compatible, and I'll use it on my network.
I have a question, the plugin doesn't work if the backend server is <1.13?

4/5 please add multiple pterodactyls and I will delete and I will change to 5/5 so please do it…

Works like a charm. Amazing plugin, that helps small servers like mine to provide more gamemodes on user request.
The only thing I couldnt find was message color formatting, you still can change messages, but not their colors, but thats just a cosmetic problem.

I wana ask where i can get support & how i can use ptla_ cuz i wana make server for my hosting

Cool idea, I definitely think that I would use this on my network if I decide to create one, but it seems a little bit hard to configure.

I do not have any experience using this plugin yet. And just to be sure, do I need to have this plugin on my paper servers in the network?

This is exactly what I needed. And it works well. .
