I agree with you on a PvE stand point but look at the forums. There are many post about specific weapons being too dominate only because they where reforgable either by IB or through HoW reforge. If HoW weapons get stuck in limbo, I wouldn't care because they wouldn't be an option for IB or ToO. Therefore, we may not have to worry about Bungie catering to the 10% that moan and groan for nerfs on weapon classes instead of blaming perfect perk roles as they should.
