#5 Asuka (WWE To Impact)
Asuka is arguably one of the best wrestlers ever who has worked in WWE, but most importantly in NXT. She made her WWE debut by starting working on the yellow brand. There her undefeated 914-days streak started.
Though the Japanese star has made her main roster debut with some impressing accolades by her side, her WWE career has already started to fade away, due to the reason reported by us, lack of English speaking skills. Also, Asuka is now seen working nowhere despite winning the first ever women's Royal Rumble match.
So, the better option for her would be to move on from WWE and try somewhere else such as NJPW or Impact Wrestling. She might find success there comparing to the one she has found on working WWE's main roster.
