I think everyone is missing the point that Bolin is tying in Varrick with the other characters, even if he's too stupid to realize what he's doing he's actually very important because he's being used in propaganda to start the war and if it weren't for him, Future Industries would never have gotten connected with Varrick and his brother never would have gone to the set and realized that the Varrick had the remote detonators used in the terrorist attacks. Yes Bolin isn't really doing anything but he is Forrest Gumping his way through this war, being everywhere important and oblivious to the significance of his own presence.
gaia_kittenstar That's what I think. He's easily manipulated and therefore Varrick got himself close to him because he's Mako's brother. He also expressed interest in something to do so it was that much easier. No one expected it until it was too late. But Bolin really hasn't found his niche yet either. His identity before was built on the team which is in shambles due to all of the things Korra and Mako are doing. So, he's sort of lost and left behind. That's a big difference between Sokka and Bolin. Sokka's purpose was to take care of Katara. That was his job given to him by his father. Bolin has no purpose other than to just try to survive. I assume that he'll eventually find it because Mako has found his as a detective.
Sokka's team never broke up because the entire series was focused on fighting against he fire nation. Its hard to break up when you know that it might in fact be the actual end of the world. This time, however, there was a break in the action. The team came together to fight the anti-benders, and once they were stopped, the tension that kept them together was lost. Bolin liked pro bending, but Korra had her important Avatar duties to get back to and Mako was all about being a detective. Yeah, Bolin got left behind, but he shouldn't have to be a detective like his brother. Don't get too caught up in him having a purpose, he doesn't really need one. The current situation is a lot more relaxed and that's what he's there for, to keep it light. If you don't get it, you need more Bolin.
