I'm just going to say my last piece and watch from afar. This will end with me purposely making a horrible suggestion.

I've reached my final verdict last expansion. My thoughts have not changed this expansion, and I'm pretty certain that it's not going to change this coming expansion. Things need changing for certain. However, for the most part it's not a balancing issue that has persisted. It's a community issue. Majority hyper focus objectives, and when contesting or collecting them isn't possible for majority of the game one of the losing team decides to help the winning team reach their goals. It doesn't matter how you change the rules. It will still persist. The only ones that will not be affected are those that are just there for the experience points. If you change frontlines to have 2 teams the only thing the losing team would do is either afk, leave mid match, or "run it mid." You can take away premades entirely, and a lot of people will get that high for a short time before finding something else to complain about, the defeatist attitude still being present in some games. I think premades are showing everyone the state of frontlines and how certain things are broken. However, if you want to see how many people care about playing frontlines or pvp in general add a surrender button. Just like everyone has the option to abandon dungeon runs and trial/raid runs give everyone the option to abandon the game without any penalties.
