But you can't prove how much or little involvement he had in abyssea, and that's that. There is no proof whatsoever that he wasn't pulling the strings with abyssea as well.

The only "proof" people have of his "return" (not real proof) is that the empy95 trial and voidwatch are more tanakaish updates. Well concidering the dev team said they were going to balance the cost/effort of relics, mythics and empyreans, they have done that pretty damn well. As for voidwatch, all I can say is you're calling out one event. I can do that too: New dynamis. Released around the same time as voidwatch. Very casual. Very good drops. By your standards very un-tanakaish.
