They didn't but once you are dead they are too busy grieving.
Haha, great reply.
That would actually make for good storyline but I have a problem with that being as their is such severe skill loss on your pets at death. The people you die to are typically players as a Tamer. When you die, they make it a point to kill your pets typically. I can understand that my pets may be grieving but I do not think that they are grieving to the point where they will sit in a field of poison while getting owned with basically no response from them. When the tamer dies the pets become basically worthless. I'm not stating that they pets should go on the offensive and by the time I get ressed and get back I have a bunch of corpses to loot but rather at least give them some AI Common sense to not stand in a poison field. Its ridiculous to the point that someone with a young dragon can DESTROY a level 6/7 meta pet if the person employs the right techniques which are very basic.
I'm kind of impartial to this because i've benefited from both sides of the equation being a tamer and having killed tamers before but I do find it a bit silly the level of ignorance our pets display when the owner has passed.
Let's say I'm riding a horse somewhere and have a heart attack and fall off and die. While my family will definitely grief whenever they find my body or get the news of my passing but I doubt the horse is going to sit there and die from a pack of coyotes or dehydration because it is grieving over my death. I'd assume the horse was very tame and a good companion for a cowboy but it is still an animal and will be an animal when the person dies.
I think it would be cool to see AI eat the former owners of dragons when they afk and let their pets go wild on accident. Have the person come back to a wild dragon and "Partially eaten remains". hah. Anyhow, just my 2 cents.
