I think it would be best for you to finish leveling your titan and try it for a week or so and then come back and see if you think it still needs a nerf. It doesn't make a lot of sense to ask for a nerf when you haven't even really played your titan. Shoulder charge isn't a win button. Honestly, you're pretty bad at crucible so I would try to focus on the things that you can control rather than worrying about shoulder charge and how it affects you. There are a ton of things to work on first before balance affects you at all. Not trying to be a jerk here but you're simply not skilled enough to know if things are out of whack or not. You typically don't see many people who are really good complain about shoulder charge and the reason is it's not broken at all. Good players can deal with it very easily. Work on what you have control over. Once you get better you'll see that shoulder charge is fine.
