With all these characters getting reworks to better suit a faster passed combat style with combos after combos and more openers the nobushi has fallen behind. She isn't that great in a team fight but 1v1 she is able to be on par with most if not all other heroes. The Nobushi is my main character and once I become outnumbered my chances of survival drastically drop.
I mean. Her zone is still considered one of the best in the game, along with Glad's, Wardens and Orochi's since they're just a free damage, no risk button to press. Try spamming zone a bit in gank fights, it'll give you some breathing room and let you consider your options (usually the best thing to do in that situation is run as fast as possible in the opposite direction)
Nobushi has long been considered an incredibly strong 4v4 hero by a good portion of the community. The recent major balance rework decreased the power of her zone a bit, but she is still quite the force to be reckoned with! We are still making sure to keep a close eye on her as we move forward with the rest of the reworks/major balance updates though. Should we make additional changes to her, we'll be sure players are the first to know!
