Since you both keep the same i prefer replying both at same time. The depiction in game from an act does not mean that is how it happened, think for example about how small the Well of Eternity is compared to the original one.
But okay, lets just concede this one, if you can simply explain to me how Jaina literally got several times stronger without doing anything at all. There is no other explanation, no other situation, no other training, nothing at all that affects her power aside from THAT quest, where she specifically asks you to bring the power of Lei Shen back and when you bring it, she says she can feel it.
She might be wrong and might be just a part? Who knows, but literally that moment, that single moment is the only moment in the whole recent wow where she has shown any attempt to improve her strength and she CONFIRMS it.
Well, Antonidas died in WC3 which happens like 10 or 15 years before? So probably he indicated that she has potential to become the strongest mage like 20 years ago... 20 years is more than enough to improve quite a lot. Also, i was just re-reading and she did not become leader of the Kirin Tor due to a profecy, she seems to have offered rejoining as a novice and the council were the ones who decided to ask her become their leader which, profecy aside, makes sense since she is way stronger than Modera, Ansirem, Karlain and Aethas, who else would have been able to take the rulership of a magical kingdom if not the most proficient mage active?
War Crimes novel is a crime itself and you know it. I havent managed to fully read it, but the fact is that she gets shoot in the back while she is fighting a version of herself from an alternative timeline... so i guess if you had to fight yourself AND people shooting at your back, you'd be dead too, even if you were Sargeras.
I agree, not knowing were Wrathion is does not make the Legion unable to find him, the fact that he NEVER stated it, he NEVER showed any damage, or that we were able to found him like we found Eonar... it gives vibes that probably Legion never found him, because Legion did not need to find him.
How did Wrathion survive then if the Legion found him? Why the Legion would leave a Dragon Aspect after draining the soul of Aman'thul from him? It doesnt make sense.
Azshara was alredy the mightiest mage 10.000 years ago, and now she is directly empowered by N'Zoth and was one of the main antagonist of the expansion. The fact that she is able to best Jaina is no surprise, it would actually be surprising that she could beat Azshara. But again, no, Jaina showed she still has extremelly strong power in Dazar'Alor, where she literally froze an entire sea for a couple minutes while fighting the Horde Champions. Have you ever seen any other mage display such raw power?
Its simple, she didnt. The fact that a developer had to answer with a question just gives a hint that Blizzard has not confirmed that fact. I mean, he could have clearly stated "Legion got into Ulduar and stole it", but he said "Didnt you saw Legion invasions?" Which honestly answers nothing.
We know that she has been taken by Sylvannas minions into Shadowlands, but as far as i have read, we dont know how they managed to pull it... also she is not the only one who has been taken.
