BB vs v3

[Hrith]

You only get one item drop in Normal difficulty, and it can be any of the rares listed, a tool item or meseta, so the odds of getting Black King Bar is rather slim.

Most BPD (official translation) prizes aren't worth obtaining, so the quest doesn't ruin the game much.
The only good prizes are Sange & Yasha and Jizai, maybe Slicer of Fanatic.
Jizai, and a few new items, are ONLY obtainable there, so that doesn't ruin it.
Vivienne no longer drops in the game, so BPD is the only way to obtain it = not unfair.

All the other drops suck:
-10 star items without % = I'd rather find my own with some %.
-armours and shields with minimum stats = I'd rather find my own with higher stats.
-the units which drop aren't good -- God/Technique and Cure units = easy drops, God/Ability = useless on BB.
