I feel like Bioware handled the "epic" feel of killing Soa in the Eternity Vault pretty well. Even though there was little backstory, you could tell this was a seriously bad dude. It certainly felt like an accomplishment to finally kill him back in the day.
But, our characters are their hay-day's heroes, I guess. Thinning out the competition. It'd just be nice to have some more fanfare around some of the more important kills.
Haven't tried any ops yet, good to know some feel ******. I feel that more than anything else that's what WoW's current raids are missing for me... I don't feel energized and angry enough to beat any of the bad guys.
