Not quite sure how anyone can defend this mentality. If Square-Enix had put Delve in the game with having a Delve weapon being the requirement to enter, and only being able to get it from the event, how many people would be complaining about how stupid that is? And how pointless having an event that no-one can do is? It may not be exactly the same, obviously. But yes... The "required" gear can hardly be required, since someone had to beat the content without it. Logic! Or something...
