Agree on both points. Look, I liked Sting way back in the day, but no one is dying to see him wrestle anymore. Sure, it was cool seeing him against HHH and really the only match would want to see Sting in is against Taker. Other than that, it's pointless. So Sting joins the Shield? That makes no sense to me.
As for Lesnar and Taker, I don't see the point either. We've seen it already. If Taker wins, doesn't that lessen Brock? And if Brock wins, who cares? I'm guessing this will more than likely be a casket match. Only way this has some significance is if Taker loses and retires.
