Judging from the video review I think a score around 6.5 would be more justified.
On the hand I watched an additional gameplay video of the battle system and it really looks broken. I hate MMO style battle systems and I would throw the game out of the window if I see the game cheating (which it does).
Overall this game went from my "buying-when-cheaper-list" to my "not-going-to-bother-list".
