Hi Floaty,
I know a couple of people who have just got WW LGW and they don't have a second language. As for waiting to go l/h, transferring fleets in BA is all about when positions become available due to things like people leaving, retirement and seniority. I certainly don't believe that you were rejected by BA because you weren't qualified, on my training course, there were 5 crew who were new to the role of cabin crew.
Happy Flying.
