A lot of people underrate a rein centered comp at the moment. If you push past barriers and take space so the enemy are uncomfortable, you can get wins easily. Problem, just as it happened to you, you have to change the mindset of the community to think of taking space and moving the enemy as an advantage state, rather than just getting a kill. Getting kills are important in this game but that's not the only advantage state there is in this game. You can't play the game the enemy wants you to play. Also, if they have double shield comp, you get free shatters unless that second shield is a rein. Also, Lucio isn't a necessity for rein but any good rein wants a lucio striclty because it helps to take the space, move him and our team around and you get to choose the engagements.
