The question, of course, isn't about that. It's about whether it's too small a change too late in the game.
Make no mistake, this is a change that is significant enough to merit an announcement, but it's one that just missed the big patch we finally received not too long ago. (My initial reaction to that is middling, for the record, neither bad nor really a break from form or something that justifies its long delay.) I would be surprised if we see this change actually live in the game before next year. And it's a change of more conceptual significance than anything else because unless someone very quietly managed to clear Datascape without telling anyone, the end of that raid has gone unseen.
