No requests for Monster Hunter World will be taken for trainers or Cosmos as this game has been permanently retired due to threat of legal action. This is why this game has been retired Permanently!
Actually, that changed today and a new trainer has been posted August 28.
See Pwiz's post about it here: Link
Yeah changed after my post a day later which I now noticed via email update. Its for offline use only people so do not use the trainer online or it could cause issues
