The rewards for the queen's wrath event really feels like a "make good": someone at bungie noticed that there weren't enough people doing the raid and the nightfall strikes, so at the last minute they swapped the mission and vendor rewards to get more legendaries out into circulation while they work on a more thorough overhaul of the loot system.
It makes no sense otherwise to grind rep for weapons that aren't any better than what most people at 24 probably have already.
I noticed this as well. The gear you get from the event kinda blows compared to things you can buy or get from the raid. The only use I'm getting out of them is legendary mats.
