Personally I think this is a pure exploit exploiting old game’s mechanics. Pet builds should get some balancing buffs instead to patch those cc-resists they are missing (or whatever they are missing). Had I played pet builds I would ask for the adequate fix for that resist problem, using an exploit because there is no other way takes fun away from the game for a lot of players. So I would be for the removal of the exploit but with adequate patches to pet resists problem. Because for permanent pets on non-pet builds this feels almost like cheating really.
