In my opinion "Allow translated techtrees" should be also visible from client side.
Just to know in which language will be battle as well as be able to ask the admin to enable or disable this function.
Today I had the opportunity to play for the first time on prax mod in German
and were it not that I played with prax many times it would be totally unplayable
.
I firmly believe that before the battle I should be able to assess the language of the techtree.
