This idea/suggestion is Open. You can respond to ask questions or discuss the idea and either vote it up or down if you believe it should or should not be implemented, respectively. Popular suggestions and ideas will be considered by the development team to become reality in-game.
Proposal
Handler needs to be within 25m of the pet for the revive to progress or the revive pauses until you are in range again and then it will continue.
Justification
Reviving a pet for over 100m away is stupid
Motivation
Balancing and making it make more sense.
Pets hurt and when you drop the pet its stupid the handler can start the revive and then sprint off.
