Lok coulda used more "filler" episodes

I know it's the fault of the troubles production but I think one of the things lok suffers from is lack of filler. I think it's most obvious w the love triangle; Mako and Korra could've had more introspective moments about how their actions are impacting the friend group even if they didn't have the restraint to stop it. Seeing that they care about asami and bolin, even if they're behaving selfishly, makes them seem more dynamic, realistic, and more like a friend group. And it would've had more space for korrasami to build sooner. I wish we could see Korra alone w her thoughts, maybe "why am I so jealous? Why can I not stop thinking about them together? Why is she in the back of my mind?" So it could humanize them more. Another example is mako and bolins relationship. We know bolin feels like a sidekick to his brother, and he even moves out and stands his ground about not being respected. But it's off screen. We don't know the fight that caused bolin to move out. That's a massive moment for the main characters that they just don't show. I try to avoid comparisons but I cant imagine them doing something so significant w the gaang and deciding not to show it. If katara and sokka had a fall out they would show us. The relationships between the friend group feels very surface level, and I think that's the fault of them not having as many episodes per season/not knowing if a new season was coming. But lok doesn't have the same cozy feel to me as Atla, and the lack of filler I think is the biggest reason.
