I'm against everyone seeing everything with no effort, but this really isn't bad at all. Like everyone has said, it's only 496 gear. You can get better gear from LFR ToT. Not to mention weapons don't even drop. Best you can do is a 476 for like 50k Timeless coins, which is a good chunk. You can get a better one from T14 LFR. They didn't even add a valor vendor for current tier normal gear.
The 496 drops are perfectly reasonable. I do think they could have made the drop rate a bit lower, but the stats can also completely suck, or you get an item not in your armor class, so it sort of evens out. They shouldn't be disenchantable though.
