Considering the number of hours and guild annoyances it takes to get to endgame, for me that $800 would be money well spent.
Even for a newly-minted level cap character, $800 would still be a good deal if I took the time I would have spend leveling and went to work instead.
Of course, the fun is in the journey. The richer the journey, the more the fun.
Yep, makes me miss my orc warlock.
