Lorewise, It makes no sense, especially in the story, The Renegade would fit SIDING with Balthazar instead of fighting him, he is a renegade after all.
Kalla Scorchrazor's Statue has a Greatsword,
Turai Ossa was known for having a large sword, which can be a greatsword now ( Fellblade in gw1 is now a GS, Turai's sword could easily be a GS)
We went to Elona., Which is more about Turai Ossa and Palawa Joko.
Kalla Scorchrazor wasn't even the leader of the warband/group she was in, She gets orders from higher up and her Elite is Summon her Legionnaire.
Basically I am extremely Salty that I feel Anet has ignored Lore and given us a random charr for no other reason than ignorance.
Please someone prove me wrong and tell me the good reasons Revs lorewise get a Charr Renegade with a Shortbow, to fight a Renegade God, With a greatsword.
(Again, Renegade God, Greatsword, Seriously... greatsword would have made 1000000000000% more sense than Shortbow, Heck they could have made it stay kalla with a Greatsword and made it a 1200 range Greatsword that you swing to apply bleed to an enemy with ghostly claws)
