If the Reinhardt is pressuring in, that leaves him vulnerable. If he does this more than once, one of your teammates can just ruin his routine with some gunfire. He won’t be able to kill you more than once, if your team has even some brains.
Just remember, if you die on attack Kings Row A, it’s nowhere near as bad as if you take him with you. He’s got a LOOONG walk back. Him pushing in, means he’s either in a huge advantage point where there’s no threat, or he’s just being reckless and will be killed quickly.
Oftentimes it’s good to get him to waste his shatter, on one of those pressure situations. This will leave your team at a bigger advantage the next team fight, if they have reserved ult charge for the 3rd exchange.
Likely if he uses his shatter, he’ll fall back to the point, protecting further in and building more ult charge. This is when you can pressure the point more effectively.
Watch out for high impact damage like Junkrat, and make sure to knock Brigittes out of the way.
If they have a Widow standing on the back mid or back left, or in one of the windows, make sure you keep your barrier up until she’s dead or forced to move. This can be very difficult, as you’re relying entirely on your team to perform actions, and fighting the front line, as well as dealing with the DPS threats on the ground, the boops, and the various support CC abilities always targeting you. But it’s your job. This can be bypassed if you have a D.Va or a Winston, as they head straight for her, forcing her out of position.
If Widow is on the right or on the floor, you just need to play patiently and take your time with the barrier drops. She’ll die quickly if she has no protection, and you don’t need to move in immediately. Just be patient.
Oftentimes once the defensive Reinhardt’s barrier drops, and hes past the choke, that fight is over for him. The man is a bullet magnet, and he’s out of position.
Sometimes Reinhardt tries to protect the left side of the statue (his left, your right if on attack), in order to get picks. If he does this, you’re likely either dealing with Winston or Orisa with him, otherwise anyone trying to hide on the point, is exposed to direct DPS gunfire. So having him over there as solo tank, is a tactical advantage for you on attack. He’s quite exposed to direct damage, barrier piercing damage, charges, and a few other things. Solo Zarya protecting point is very vulnerable unless she’s hiding in the doorway, or center point space, or back behind the point. All 3 of which are a huge disadvantage for Reinhardt on the opposite end of the statue.
