Alliance betrayel of Blood Elves which resulted Blood Elves losing 90% of their population is much worse then Sylvanas retreat, but i dont see Horde or Blood Elves asking for payback or revenge.
Alliance had leaders even more racistic than Garrosh like Grand Marshall Othmar Garithos, but Horde was fighting vs Garrosh in their own city, and Alliance wasnt fighting against Garithos.
When doing quests, I see humans and Alliance invading and attacking Barrens and Durotar long before bombing of Theramore, but i dont see Orcs ,Taurens or Trolls asking for Revenge.
Characters like Jaina and Genn Greymane saying that Horde betrayed them and want Revenge, Alliance betrayed Blood Elves alot but Blood elf characters doesnt asking for Revenge? (expect maybe female belf voice npcs sound "We will have our revenge" )
And Lor'themar Theron wanted to join Alliance during MOP? After Human & Alliance Army didnt helped when Scourge was attacking Blood Elves, and after Alliance used Blood Elves as cannon fodder.
Im not saying whole Alliance obssesed with Revenge, but certain characters like Genn,Jaina and Rogers, and Alliance soldiers in Stormheim quests.
Why its so one sided?
