Gennâs attack was personal and not really representative of the whole alliance, and he knew beforehand she was up to something.
You should also consider the fact that there was never any closure between them after she nearly slaughtered his people in Gilneas.
I find it odd that people even defend her like I get that sheâs your horde warchief but come on nowâŠ
If he hadnt stopped her weâd be 10x more doomed.
Orgrimmar wasnât being attacked with Jaina thinking of greater military strategy or to break the Hordeâs infrastructure, it was to wipe out orcs.
Sylvanas is always being evil though. Thereâs evidence in game that he had some suspicions about what she was up to. This is further backed up by the fact that he attacked her, but then destroyed the lantern and left.
He did nothing that would justify the slaughter of thousands of night elves, not to mention the other beings that died in the tree that had nothing to do with the war.
She didnât have to follow orders to attack gilneas. Heck, she didnât even follow the orders to not use blight while attacking.
For the entirety of the game sheâs done whatever sheâs wanted with no consequences as well. She deserved far worse than what Genn did, and the night elves did not deserve genocide for his actions.
True, but as an Alliance leader his actions do represent the Alliance.
Did he? I didnât know this.
Oh Iâm not defending Sylvanas at all. I literally said she was being evil.
Iâm not saying that wouldâve excused the burning of Teldrassil. But it wouldâve been a better reason to invade than âWell, if they hit Orgrimmar first weâll probably be in trouble, so just in caseâŠâ
It doesnât help that at the time, Blizzard framed it as if it were a spur of the moment spite decision instead of part of her plot with the Jailer.
Regardless, I donât think she should have drowned Orgrimmar either, but it was a valid military target. If genn attacking sylvanas, not even aiming to kill her, justifies her throwing a tantrum and burning thousands of innocents alive, then Jainaâs motivation doesnât matter. Orcs nuked Theramore. Sheâs not allowed to fight back because sheâs pissed that her people died, but sylvanas can commit genocide in response to not being allowed to enslave someone?
Well considering every horde leader in BfA had their own way of representing the horde during BfA, I wouldnât hold Gennâs actions as representative of the alliance as a whole either.
During the quest in aszuna with the forsaken shipwreck he discovers her motives, I donât remember exactly what was written on the missive though.
Iâm sorry for misinterpreting your stance then! 
No, the burning of Teldrassil was obviously wrong, and anyone who says otherwise is a straight up fool.
Sylvanas claimed she was only invading to subdue it militarily though, an action which couldâve been justified by Alliance aggression.
The whole thing just feels bad to me. It still irritates me she had so much horde support after, to the point where Saurfang wasnât sure his forces combined with the alliance forces would be enough to stop her.
Then she farts away after calling everyone losers and somehow everyone is off the hook except for her.
Orgrimmar was a valid target. Which is why the Siege of Orgrimmar wasnât an atrocity. Attempting to drown the civilian populace out of spite is not a legitimate military objective.
One is an atrocity, one is war.
I have never said it did. But Genn is partially responsible for what happened. If he hadnât attacked Sylvanas she wouldnât have been able to burn Teldrassil.
Okay then Theramore is perfectly justified because Garrosh was pissed that his people had died to the invasion from Theramore.
Drowning an entire cityâs population for spite is not the same as bombing a military port being used to invade foreign territory.
But if she hadnât attacked Genn and his people, he would have had no reason to attack her. Or are members of the alliance never allowed to react?
In a previous war. By that metric Teldrassil was fine because the night elves struck first against the Horde.
Bitterness is not an excuse to attack an ally.
ââ 
for Void elves please. White, red, black, browns as well. And ability to modify racial to be invisible.Âł
Well, I donât know if they considered each other allies after the Broken Shore, but they were still both fighting the Legion.
But he knew what she was up to. Itâs not just bitterness. It contributed, yes. But like I said, he attacked her, but then destroyed the lantern.
As he walked away he said she took his sons future, so he took hers. He knew what the lantern did. He knew what an enslaved valkyr would mean for her.
And before that, she left allies in helheim while making her little deal with Helya. She can act against allies and abandon her own people but he canât stop her from putting in an infinite lives cheat code?
They were fighting joint campaigns as seen at Suramar. Thatâs usually the sort of shenanigans allies get up to.
You can do this right now by macroing /cancelaura Entropic Embrace to your abilities. Youâll lose out on the dps increase, but still, itâs possible right now.
As youâre a mage, Iâll use Frostbolt as an example:
#showtooltip Frostbolt
/cancelaura Entropic Embrace
/cast Frostbolt
All he knows is that sheâs after something important. As far as Iâm aware he didnât ever specify what it was.
A vague suspicion is not a good reason to attack an ally. He didnât even try diplomacy, he went straight to ambushing.
And she went straight to working with an enemy to enslave someone.
Yes, but thatâs post fact justification.
But in the middle of storm stormheim we saw her making the deal with Helya.
