Maybe nothing at all has changed? Have you considered that the glitch might have been in DR all along, and we are just now discovering it? This glitch works in both Andriod AND ios, it is much easier to hit in ios. Look in the latest DSRs and you'll see that (some of the best shifters in DR) have hit these amazing shifts on an andriod, making them win by incredible amounts.
How do you explain that the exact same tune for an ios device will now run faster then it did before? Run by the same people? The only way I can explain it is that there was some sort of change.
