It's sad but I'm afraid you might have some difficulties in being recruited. I haven't heard of any BTB French team that recruit English-speaking players. The thing is, if you were to play with a French btb team, during a custom match, your teammates wouldn't bother speaking in English because they can't do it but mostly because they needn't do it as Halo.fr btb is a French BTB championship. And even if some of them could, the communication would end up being messy since it'd be a mix of French and English. But perhaps you'll be lucky and run into an English-speaking BTB team that I don't know of but it's very unlikely.
