The most recent Diablo IV Gold cinematic trailer from Blizzard is a scene of Inarius in a battle against Lilith Armed forces at both sides. Although the scene doesn't show Tyrael's direct involvementin the story, his development of Horadrim and the influence he has on the Paladins of Sanctuary implies that he's definitely in the game. Dark and light battles in the battle, and the sadly dead Tyrael sits somewhere in between.
It is highly likely that his presence will be felt through these intermediaries unless circumstances cause him to act. Tyrael still feels the repercussions of the destruction of the Worldstone at the conclusion of Diablo 2. That mystical artifact protected Sanctuary from Heaven and Hell and now stands as protector over the land as its successor. Tyrael doesn't appear to be leading any further charges into Hell or take his fight any further in to the Pandemonium Fortress, where he may offer advice like Deckard Cain to those who stay and listen.
Five classes playable in Diablo have been released so far and all of them are variations on the options offered in previous games. In the sense that each installment has been different and exciting, maybe Tyrael could become a hand in the battle in the battle, helping to balance the sides by providing players with the possibility to acquire angelic or demon powers , in exchange for responsibilities to Sanctuary. This kind of strategy is likely to be similar to the multi-tree progression that was already confirmed for the series.
It is unlikely that Blizzard intends to turn Angels and Demons into classes as the franchise centers those trapped between their ways. As a mortal trapped between Heaven and Hell Tyrael occupies a position unlike any other in all of Diablo legends. He's more likely to play acting as a balancer in the story, or even the voice of reason instead of taking sides like his former self. Even when he is forced to take sides, Tyrael now understands his role as a mortals, which is the way he is likely to participate in the events of Diablo 4.
Blizzard's strategy for speccing your character in Diablo 4 is a blend of the style of the studio's Diablo 2 and Diablo 3. As the executive producer and head of the Diablo franchise Rod Fergusson put it, "Diablo 2 seemed like you were locked in. You could respec one time per difficulty. In D3, you kind of changed your look like you would change your clothes. Everything was gear-based as opposed to skill-based."Fergusson added, "I think the fact that we have skills on the equipment [in buy cheap Diablo IV Gold is really nice for experimentation -- as a sorceress I [might] get Blizzard [on a pair of boots] three levels before I should and I can try Blizzard to see if I actually want it."
