Turning Batista heel was the best thing for him. He's still not really in ring shape, he can't fight a singles match with Sheamus full of rest spots and not look ridiculous. Now, he got to be in one of the greatest wrestlemania main events of all, being booed like a true goddamn heel should be booed, having a match that didn't demanded him to do more work than he can handle and still be a very good and exciting match.
Now he still is a damn good heel, he still is being protected by having Orton and Triple H carrying him and just letting him out to do some cool spot like the bomb into RKO into monitor accidental friendly fire finisher. So now he still is in the spotlight, first feuding with The Face Of WWE Daniel Bryan, now feuding with The Hounds Of Justice, possibly main eventing Extreme Rules as well and it is working, slowly, but it is working, people are starting to boo the character and not the man or the booking, people are starting to see him more as a threat and less as someone who almost faints in a match, because he is not in those kind of matches anymore, he is the guy who comes in fresh, does a finisher, stomp his feet so the crowd can boo him and hope for the face to make a comeback and then get out.
He may have not got his main event babyface push as he wanted, but aside from Trips and Steph, he is pretty much the top heel right now, which is really not a bad spot to be in.
