Well it had to come, and personally I am a big fan of the Adventurer's Vault so I thought I would bite the bullet.

I suggest this is something we take out time over. I believe we should come up with a list of potentially problematic items, derived from our own limited experience and from various forum posts, etc., which we can persuse.

Personally I believe that some of the most problematic items are those that have effects which technically do not require the weapon to be used. For example Bloodclaw weapons at will power is simply used on an attack, not an attack with the weapon which I feel it should be rerequired. Personally even with that caveat I still regard Bloodclaw weapons as problematic and worthy of review.
