I could cobble up a few glances of characters looking at tables but that doesn't mean they are going to marry furniture.
Korrasami's biggest flaw, and really LoK's biggest flaw as a whole was that it was really only 1 season to start, there was no plan for what comes after. Watching s1 alone you would have never guessed that pairing unless you have a big thing for girl x girl ships. From the get go Mako was the planned love interest, him being a good one is up for debate but he was the guy. It always felt to me their break up was a way to appease the fanbloggers, who don't always have the right idea on how to do things. This is especially obvious in season 2:
You don't like Makkorra?: Fine we'll have them break up, and then let Mako dick around Asami some more
One location is boring? (no it isn't): Fine here is a lot of the Southern Water Tribe
Not spiritual enough?: Here all the spirit you can handle
When this series is allowed the time to set things up (seasons 3-4 and all of Last Airbender) it does so wonderfully. I'll admit Korrasami had it's moments in s3-4, they were good moments and not as obvious of course as Makorra in s1. I do think it's oddly appropriate that assuming Korra is going full lesbian neither she nor this series will have any future offspring. The creators are done, they gave their most vocal fans exactly what they wanted even if it was never their intention to do so. I would have admired them much more for sticking to their guns and stepping up the writing and reasoning in response.
The actual finale sans shipping however was everything I could have asked for, everyone had their moment in the sun. Team Airbenders did a heck of a job showing how much they've grown, Wu does the right thing despite showing he may not have been the absolute worst leader. He fixes the independent state issue. Mako and Bolin have such a great engine room scene, Bolin not agreeing but accepting what must be done was something LoK could pull off that the Gaang wouldn't be able to do. Korra delivers in the end a great transformation into a capable Avatar. Ten minutes in I was shaking, this show may not be perfect but considering how dicked around the Avatar series was it's the best we could have gotten.
EDIT: Yea Faint I'm aware which is why I say 3-4 was good stuff, and it would have been nice to see more of that support.
