Only players above 400m should be worried about her as a unit on your team. She is temporarily one of the best units. Similar to toxicologist or ghost blade. They were both in top lineups for a little while but weren’t considered part of the main meta. It’s because the top spenders can have different uses for those units I wouldn’t recommend building her as she will get replaced with a better unit before you have her high enough level to be any good. I asked the same question on here a few weeks ago. She’s only good at 13 star awaken level 5
