question: Is it feasible that BC and WotLK suffered in some sense due to each game's clear antagonist? Or maybe because there was no significant twist in the story so these fights seemed a bit anticlimactic. Players knew they would ultimately face off with (and in all likelihood kill) Illidan and Arthas respectively- so no real surprises. You even knew where they were sitting waiting to be killed (in their ominous base camps)
My thought is this- Blizz didn't unleash it's well-known baddies in vanilla. Players sort of 'unravelled' the story, determining who was the villain was kind of fun. This is probably a result of having played for only a short time, but I really had no idea there was a Firelord lurking in some giant fiery cave below Blackrock Mountain until I got there myself. My main point is this- secrecy and intrigue was kind of cool from a lore standpoint. Not only that but blurring the line between good and evil a bit. It is satisfying to have a clear enemy, but after Arthas and Illidan I'm a little hesitant about a game where Deathwing is the ultimate evil and every boss on the way to killing DW doesn't matter too much. I'm looking for some epic betrayals or twists- maybe i'm not alone?
