I've said this a couple of times, myself. Rather than complaining about premades, people should just try forming their own premades. It's not something that requires special skill.
Let's suppose that SE does get rid of the ability to group-up for Frontlines. First, you're absolutely going to get a lot of people complaining that they can no longer play together with their friends. Second, you're still going to get destroyed by teams that just have better players because, regardless if they are in a premade or not, they know how to read the flow of battle, figure out what to do, and then execute on that. They know how to look at their map; they know how to stay grouped; they're better at using their skills; they're better at prioritizing objectives and targets; and they don't just run away from every single fight just cause 1 or 2 frontline melees charge forward. At that point, there's really nothing left except to accept your own deficiencies, and I say this as someone who knows that he sucks at the game. However, I'm not going to cry to get rid of premades. I'm just going to try to get better at my own playing.
