Now, hear me out: the White Lotus are not government officials. They are traitors and spies and are some of the most cunning and powerful benders the Avatar-verse has ever seen. In light of that, I would propose that there is no way that, after Korra's attempted kidnapping, that they wouldn't have taught her any subbendings they could have.
Korra should have been an absolute tank.
Lightningbending first of all is nearly a one-hit kill against any opponent. That should have been first on their list to teach her. That and redirection given how somewhat common lightningbending is.
Next, metalbending should have been high on the priority list. Like way up there since, like lightning, not many people have a counter to it. Less than lightning, in fact.
Controversial, but I think Katara should have also given her a crash course in bloodbending. Enough so that she can break out of it just in case it crops up and with a warning that if she ever uses it for anything other than defense, Katara herself will come kick her ass.
I'll say lavabending was too high concept even for the WL and combustionbending is near suicide to learn so not those. But sandbending, glassbending and vinebending should have been in her arsenal. They would have turned her into a weapon.
With this, we keep to the story where Korra is the most stacked avatar in history in a world that does not need her. She can body Amon no problem, but the people don't want her to. She has to win them over before she can face him with any kind of public support.
Season 2, I'd change the lore to have both Raava and Vaatu inside the Avatar and that what Unalaq did was rip Vaatu out and left Korra comatose. Her team then have to go into the spirit world to basically reboot her, but now she's only got Raava, the spirit of pure order inside her and Raava hates the idea of Republic City. To each their own and so forth and so the team has to double back and try to get Vaatu back inside Korra else she nuke the city.
Then season 3 would have the red Lotus coming to take their shot again, but get absolutely manhandled because Korra is a beast (and one of like 5 people alive who know how to fight an airbender. Zaheer isn't special). It'd be another political intrigue as they just go underground to try and take out as many world leaders as they can before Korra catches up with them.
At this point I don't even see how season 4 can happen, but I'd like to see Korra basically trying to establish a theocracy in her own little part of the world; essentially trying to hold on to relevance and still suffering from having Raava alone run rampant in her body for like half an hour that one time. Then she sees what Kuvira is doing and has an "oh shit" moment as she realizes she's the bad guy and there's no real reason for her to be trying so hard to dominate people. Something to that effect.
Korra shouldn't be losing fights!
