They are certainly aware of the issue of them dying too fast now. They are aware of your proposed solution because people bring it up regularly and they went into quite a lot of detail about it at a fan fest. They are more likely to address it if there's sufficient feedback and discussion about it. Don't expect them to address it until at least 5.x though.

For now, if you want them to survive longer you can:
  • Not pull them.
  • Spam heals on the MT when pulled.

If you don't want to miss a hunt, you can:
  • Find them yourself. You can't miss what you found.
  • Spawn them yourself. You can't miss what you spawned and found.
