When did any of the things related to wrathion happen?
Last I remember hearing anything about wrathion before bfa was in mop. Did all the stuff happen back then?
If not where? Anduin refered that his father is dead because of wrathion. I dont recall any of that. I recall gul’dan killing him during legion events?
His agents have been everywhere in BFA (war campaign, nazjatar, BWL ect) and his return should be explained in 8.3
Overall he doesn’t want to be deathwing 2.0 and don’t really likes the return of the corruptor
Edit : if you talk to his agents they will tell you that he has been looking for the dragon isles
If you did the questlines in 8.2.5 you have a scenario where you save him from some old gods mobs in kharazan where he was looking for knowledge to fight against the corruption
That explains it. I didn’t play mop much. I was only aware of that traitor bronze dragon or some such. If wrathion too had something to do with that, then it makes sense.
