Not really.

She's definitely insanely expensive in general, but when compared to the prices of most premium characters, she's not bad at all.

Minato was the exact same price the first time he arrived, as was Sarutobi, if I'm correct. Hokage Tsunade is worlds better than both of them and is a ninja that's end game.

If you have the money to spare, she's worth it, but that's the catch: "If you have the money." Hokage Tsunade's insanely good. Not many people are meant to have her on the first place. She's a reward to those that are willing to dish out that huge amount of money for the game.

Oh, I forgot all about that wheel lol
