this girl can only rely on Korra for spiritual advice...

lol, lmao, new girl is beyond screwed. Korra had Tenzin, her own parents, the White Lotus, and all of the past Avatars up until a point for advice, although even with all that she still never heeded any of their words.

Speaking of Tenzin, one of the few moments I really enjoyed in s3, and yes I was masochistic enough to be watch all 4, was Tenzin vs Zaheer. Up until that point Zaheer had been beating everyone he fought because nobody really had proper combat experience vs an airbender any more. Except Tenzin, who not only is the sole living airbender at the time to have been taught by an actual master, but who was also trained by the previous Avatar seeing as how both were his father. Meaning he has faced both highly skilled bending abilities from the other elements in general, but likely also when combined since Aang would be able to do just that and effectively stand in for four opponents just by himself.

So Tenzin not only demolishes Zaheer with almost minimal effort because as good as Zaheer is he's so outclassed it's hilarious, but Tenzin came close to doing the same to most of the other Red Lotus members at the same time until the combustionbender sniped him. Unfortunately it was about the only time Tenzin got to show off apart from his revelation that he is not his father and should live as his own man. Easily one of the best characters in the Korra series, although for better and worse that didn't end up being something difficult to achieve.
