I already made a post some months ago about that.
The “Daily News” in Halo 5 are to 80-90% in english and really - not everybody is good in english.
The whole game is - even compared to Halo 4 - the most unfriendly non-english speaking Halo Game I`ve ever played.
Some maps still dont have german/french etc descriptions and german translated textes like the "diamond" arena rank is called "Raute" and not "Diamant". Do you use google translater or just people who dont know how to translate english-german or english-french?
Day per day I`m more done wth that game…
