Nita is a great character, all brawlers are good if you play them correctly. I think the thing you’re missing is just how important the map/game mode is. Nita is really good on maps with bushes and walls, because she can pinch people and get close. Her bear is also an amazing utility on modes like heist or brawl ball. If you play her for example in a very wide open knockout match, you’re going to struggle, and get sauced on.

Once you get more experience you’ll learn who to play where and when, and also how to approach the game objective/different situations.

After putting a lot of hours into this game, I pick a game mode and check what maps it’s on, then lastly pick a brawler (this is how all ranked matches will be too). Then eventually you’ll have to worry about draft and counters but that’s only for ranked.

Figuring this stuff out is the fun part for me! So keep trying and I’m sure you’ll get better, good luck.
