Better? or will NOTHING I say satisfy you as my opinion having any grounding.
Given you didn't have anything before beyond making broad sweeping claims with little to nothing backing them up, this is better than nothing, though the caps lock seems unnecessary.
I also notice you cut out the majority of my response and robbed my question of a great deal of context :/
S1 ended with his declaration of love and his life in shambles. We follow up as he tries to maintain the relationship with Korra AND pursue and new leg of his life (like his brother) where he makes more and more decisions that risk isolating him from people whose acclaim or approval matter. This leads, strongly to him being arrested, broken up with Korra, making alliances with the Triads, framed by a powerful business magnate. All decisions he makes and issues he must deal with while dealing with the REVERSE of his fortunes as the promising rising star who Korra was falling for
Bolin was SEEKING validation and found it exploited by two other people and gained stardom while willfully ignoring, though mostly missing, his complicity in war profiteering/propaganda scheme. Eventually comes to reconnect with his brother and RESCUES THE PRESIDENT and become a movie star with mixed results for both. Also that whole nearly yanked to the altar allowing him to level up his charisma and charm to help turn the people of Republic city against Unalaq to prevent further restriction, free them when imprisoned.
S1 ended with Asami having been left for Korra by her romantic partner in one form or another, her life in shambles because her father was a criminal who got her driven out of her own home and tried to murder her and she was left with a now failing company she was desperate to protect as she tried to rebuild her life. These are apparent;y not important or worthwhile character beats but Mako's unhealthy argument filled relationship with Korra, trying to be a cop and Bolin wanting validation and being played by Varrick are?
Also just like Bolin saved the president, we have Asami helping save Korra's father and the other rebels to the point of crashing a plane mid-flight to serve as a distraction, defeating guards ETC.
And that's just in the first few episodes.
Are Mako and Varrick involved in her story? Of course they are, its an ensemble cast, that doesn't invalidate her as a character or her presence in the story.
Varrick and then Mako deal with most of Asami's plotline about dealing with the fallout of Sato's arrest popping up to offer an issue for Mako to fix start redating him AT her initiative and then leaving Mako in the lurch after falling for that blatantly false and unconvincing set up
She, of course, like Bolin is portrayed as a rube, wears and deals with the ire and complications of her moving in on Mako, and turns all the armor and arms she was supposedly going on about to war plot
How is Varrick, the antagonist she was initially trying to align herself with not knowing he was a threat, being involved the same as him 'dealing with her plotline' when the focus and development and emotions are on Asami and Mako only got involved somehting like mid-season? He was arrested, what was she meant to do? She explained going to the prison was painful because of her father and while unconvincing to use as outsiders it would be less-so in universe.
Moving in on... You do know he told her he broke up with Korra right and was the one who refused to tell Korra they had started dating again.
Nope Varrick sold the arms to the SW, without her knowing btw, shoots daggers at Mako for not immediately correcting his violent GF while in the middle of a crisis (again) doesn't do something so gauche as have an argument or tell Korra herself in Mako's defense or just because she has non-attractive or pleasant emotions. She does fly the plane a few times but that doesn't feel like something that developed out of her actions or experiences. And we could have brought Iroh or had Bumi pull that off or someone else. She isn't a rube or weak she's wronged.. kinda She exists to complicate things but not entertainingly or even appreciatively as Varrick does.
She and Korra agreed giving arms to the South was a good idea. As to the rest, it feels blatantly aggressive mis-representative and also is very hard to actually understand, though the constant insults to Asami's character based on her background make it seem you aren't really approaching this from an, well, 'fair minded' perspective.
Also as to your "They could have had someone else do that" you know they could have had someone else, like say Lin, be the suspicious cop right? Also not developed out of her actions or experiences, you mean like her being an inventor/gear head and one of her first scenes of the season being her flying a remodeled plane?
Also your personal enjoyment in her 'complicating' things is not indicative of anything, I feel like Mako was just there to force a straight romance and make arguments and drama happen, that doesn't make it a fair or accurate assessment of his character, nor doe sit make me right if I say hes not entertaining the way I find Asami or Varrick entertaining, don't mix personal opinion up with factual assessments.
