She was never good on the mic even in Spanish, so give her another language and you get the BS. Learning a language can be difficult but if you're getting paid a lot of money to literally work in a place you need to know English you better make sure you learn. She has the money to hire the best personal tutors. She's just lazy as fuck and doesn't give a damn. You could've excused her when she first joined NXT but she's been there for a year and a half. She should've been learning.
She only made it so far since she's hot, is decent in the ring, has a coomer finisher and cool ring attire. But without a good enough gimmick/personality she's going to do badly.
