They were mildy entertaining the first time but after that the VO's are just a chore to listen to. Boss mechanics were also generally umm well.. non-existant and the few mechanics that are there are very uninteresting.
"The story runs 1600 hours"
LOL 90% of that "Story" is generic fetch/kill quests. And 200 hours per character is a huge overstatement. Maybe if you're going afk 40% of the time I could see 200 hours.
No one is asking for a perfectly complete and fleshed out endgame at release, but that doesn't change that what little endgame there is was so poorly developed/thought-out in the first place.
