The mursaat aren't evil, just misunderstood, the reason they sacrifice people on Bloodstones is to keep back the Titans which imo are considered worse, granted killing humans for anything is bad, but they see it as necessary.
I hope we get a Seer hero in GW:EN, i want to see those guys fight!
well if they're anything like the seer NPC in the Hell's Precipice mission, where 9 times out of 10 ettins kill him before you get to him, i dont hold out much hope for him. lol jk.
