Immortal pet : GW Submissions

if you are a ranger and u want a good pet i suggest u go to the prizewinning hogs in pre-searing (in ashforb abby). he will not get hit, in the beginning he is kinda useless cause of his low lvl but later on in the game he can be of great help.

How would that work in pvp? Damnit my ranger is too nasty to delete :/
