It sounds like your team's culture is built around a small dev team with a high level of autonomy and trust, which hasn't scaled to a larger org. Now's the time to establish a new culture.

Unless you are Milton from Office Space, you're not the only one on your team blocked by process (If you are, Amazon has great deals on bulk accelerants). Put out some feelers for others in the same situation. Junior team members are fertile waters. Schedule a twice-weekly recurring meeting to review one another's contributions. With discipline you can review two twenty line changes in an hour. Homework is unlikely to work here, or you wouldn't be posting this. In short order you will not only be pushing changes, but establishing yourself as someone who Gets Stuff Done.

Above all, don't sit at your desk and weep bitterly that nothing is merged. Stand up for doing things; either your team will improve, or you won't need someone else to tell you it's time to move on.
