In player vs. player designated zones, you will still be viewable and attackable by players, but you are not left completely defenseless. While engaged in a Pet Battle, any attack from another player will break you out of the battle. You will receive a 3 second damage shield that will absorb 50% of incoming attacks. The same exact wild pet that you were previously battling will respawn after you come out of combat with the other player. However, if you defeated the primary pet in battle prior to leaving the match, the pet and its team will not respawn.
Regardless of the brotherhood shared by the Illidari in their single-minded mission, there is a level of disconnect between Lord Illidan’s demon hunters and the rest of his forces. While this is by no means enforced, it is basically self-imposed by the demon hunters themselves, as the blood elves inhabiting the Grand Promenade had no issue to Vandel spending some of his free time there with their denizens. Furthermore, the bond of brotherhood is not as strong as one might expect between two demon hunters, as during their training and sparring sessions, there is nothing that stops one party from killing another so long as they maintain control of their inner-demons. Just the same, there are those within Illidan’s forces that zealously believe and follow his teachings, mentality, and machinations without question but it is not wholly uncommon for some demon hunters to either question, doubt, or even outright disagree with their lord’s ideals and methods.
If your pet's health gets too low or its attacks aren't very effective against a certain combatant, you can always switch out your current pet with another companion on your team. Only pets that are considered active (i.e., those in your three Battle Pet Slots), may be switched in and out during the battle. Once the match is over, you can always change up your active pet team, which is useful if one of your pets is low on health or dead.
The Inquisitors are something that are being unveiled with the Legion's full scale invasion as well as our own invasions and treks into the Legion's worlds. I don't know how common or how many encounters there might have been with them in the past. However, with the Nathrezim, I will say that it's probably one of the ones I would stay away from. Although, there is the argument that the Nathrezim are a race of demons and they quite clearly are not all on the same level of power as Tichondrius. So, if it is done well, described in the manner of it not being some uber-level demon, then it's feasible.
Unlike their night elven brothers-in-arms, the blood elven demon hunters have only one true avenue to their becoming what they are: the Sunfury. What this means for the character is that they were part of the coalition of elves to follow Kael’thas Sunstrider away from Quel’thalas in the wake of the Sunwell’s destruction. These same elves were present (and survived) the attacks on Northrend by Illidan Stormrage, Kael’thas, and Lady Vashj as well as the conquering of Outland through shackling Magtheridon. The Sunfury elves who had either proven themselves capable enough, sworn vendetta against the Burning Legion, and remained loyal to the Illidari in the wake of Kael’thas’ betrayal would prove capable of becoming demon hunters in the footsteps of Varedis Felsoul, the first blood elven demon hunter.
I used Zygor for legion and BFA, used AA on an alt for BFA. Personally i like Zygors format more. I like being able to target things like achievements. I used Zygor to get my Mindworm and my Lucid Nightmare as well as finish the Rep grinds for the allied races. I have zero complaints. My experience was great. I also used Zygor for some professions, recipe acquisition, a couple mounts, all of the Suramar quest line. Thank God for that. And for the last zone of Draenor on my Demon Hunter.. i forget the name.. Whatever the big daily hub thing was called.
