So I have a 3 man bladeguard unit with kor'sarro, and they have died before I've been able to use them in the three different games I've played with them, the first time I used them they were in an impulsor and got into melee with murderfang from the space wolves and got like completely destroyed and barely got any wounds off him, in the second and third games, they got completely obliterated by ranged heavy fire. People have always hyped up bladeguard, especially with kor'sarro, so am I making bad decisions or am I just going up against wrong opponents.
