I think it would be helpful if there was an easy way to capture wild mobs an release them where you please to make it easier to move them back to your base. I did a little googling and found a couple pre-built plugins that can do this: ✅ SafariNet - Premium Mob Catcher plugin | SpigotMC - High Performance Minecraft and a free alternative: Pokeballs | SpigotMC - High Performance Minecraft
This sounds laggy af... Also if you want to play Pokémon on Minecraft there are servers for that. We are a farming eco server, not a pixelmon server. And you can just use a lead, boat or just kill mobs.
Would not cause lag. Sadly there are documented issues between these plugins and the async mob tracking we use. Spawn eggs in points shop would be the best option to move/get mobs.
