I really do. Level 1-20 were cool. I remember the sense of awe i had levleling a blood elf, I didn't want that vibe to end at level 20, but it did and i had to move on. Problem is it never came back ... even after some astonishing results, the story isn't continued.. I would love that to change in a focused way.
Sure I got to see the blood elves again, but it was to feed whatever the main plot was, almost as if someone decided oh, "we should use blood elves here", and while that was certainly better than the Troll ignore treatment, or the Gnome treatment of nothing, or the night elf treatment of constant destruction destroyed - it is still not what I really wanted.
Would it have been impossible to have each expansion have about 1 -5 levels worth of content that continued telling a race specific story - and it could definitely include the new continent, but rather than blood elves serving the expansion plot, the blood elf campaign would continue the blood elf story specifically with respect to the blood elves.
Fast forward to present - how do you think they can do this?
