Who is your biggest 'regret' pull in the game now that 3 years have passed?

The game is about 3 years old. With so many characters that have come out, who would you say you regret pulling the most and why?

For me? If I'm honest it's Ye Shunguang. I was a fool who was persuaded by the void hunter title and marketing. She is strong of course.....but I find her very boring to play. Absolutely my biggest mistake in this game, got her at hard pity after losing a 50/50 too.

No shade to Ye Shunguang lovers, just my own feelings about her.
