Ok, I've gone through the french version of the Deathwatch core rulebook and there are parts really well translated and others, not so good... Anyway I don't think the french version is responsible for everything, for example : the game let's you dodge weapon fire but, in the movie Ultramarines can you see Astartes rock and rolling all time to dodge fire ? Just once when Severus and Verenor drop under that land speeder... Most of the time they don't move at all when firing so I think this rule has to be modified. How many times do you see marines reloading in that movie ? Not once !
I'm not going to talk about everything I noticed but the high jump rule is also nonsense when it let's you jump more than 5 meters high in the air with a run start. Notice also the big differences in the jumping rules between high and long jumps if you have a run start or not : without a run start a marine cannot jump high but he can jump almost as far as if he had run !
Anyway, I'm wondering how many of you use house rules because I think I'll have to remake a good part of the rules even though I admit they're a good base to work on. Some good ideas there too...
