Every time the discussion about pet warp come up its important to remember that pet warp does not solve pet attack problems.
The two main pet attack problems are:
1. Tell a pet to attack and it goes in the opposite direction and gets lost and stuck.
2. Tell a pet to attack and it pressess against the side of the wall forever because the Mob is directly on the other side.
Oh! Why not just go in the Mob room and do a pet warp then? Because often the strategy of pet users is to have the pet attack while the owner stays out of the way. That means the pet has to be able to navigate well enough to make it to the target without warping.
Yeah, pet warp would be an improvement and save a fair bit of frustration, but without fixing pet attack pet owners are still going to die while their pets are off doing nothing someplace else.
