Practicalness of Kyokushin Karate

Ok so i tried a self defense karate class called kokondo and i hated it there was no fighting to it and it made me realize i love the fighting type of training and lately ive had my eyes on kyokushin karate but im not having much faith in it sence its designed for sport and how they neglect blocking lunches to the face but is that really a big deal i mean if they can block punches to the stomach why not the face and they also have to block kicks to the face as well so i wanted to know what you guys think of kyokushins practical usefulness if you had to defend yourself
