Well of course she practically soloed Black Zetsu and the summon thing. Well Oro and other did help out. I am really pissed though because this may or may not shock some of you but I have rated Karin as my least favorite Naruto Character. And out of all the main anime or manga that I enjoy she may be my least favorite character out of all the series except for some minor or of course filler arc characters that I don't count. I'm sorry if you don't agree that in the very least shes a bad character I'm only saying this is my option.
Sasuke is a horrible character don't get me wrong. But Karin is on a whole other level. Yet shes really strong all of the sudden in the series and I am not arguing that point at all. It still does not make her a better character.
Yes however there has been a couple situations like this over the past 40 chapters. Still it's good to see. Personally what I miss the most from pre-shippudden or early shippudden is Ninja doing Ninja things. You know jumping from branch to branch in the forest. Marking there path, hiding there tracks, following the tracks of the enemy. Stalking, spying, ambushing.
None of that exists now. Ninja A is like I sense the presence of Ninja B coming from miles away. I will challenge them to a duel! It's basically DBZ at this point. However it's DBZ with decent or even good team work and team battles so you know what it's fine!
