I came here to read about the buffs that put her over the top? Which specific buffs? Sounds like you need to work on the match up?
Lots of characters in this game do big damage,
Lots of characters in this game have mix
Lots of characters in this game can burn meter on specials to stay safe,
Things Nitara doesn't have, that other characters have,
Can't combo off Throw
Horrible wake up armor
Under 1000 health if you don't use Ferra/Jax/Tremor
T-rex D1 that lots of characters can blow up in the poke war,
The ferra stuff is fake on block, she has a massive hurt box that lots of characters can clip in a lot of situations,
I won't sit and say she is bad,
But the term broken is thrown around a little too much these days, and Nitara is not broken.
The devs didn't listen to fans and think "oh man, this character we built from the ground up and know every in and out of is bad, look guys, everyone says she is bad"
Maybe they looked at the data of which characters are used most, and wanted to get that to a little more broad then Johnny Cage and Raiden,
Food for thought, patience is key when fighting most Nitaras, they will hang themselves eventually,
