Being a new BlazBlue player myself, I can totally understand how you feel. However, you shouldn't let online intimidate you. Losing will happen, it's inevitable. You just have to learn from those loses. The one thing I used to do is just play with friends in player matches first instead of going off into ranked. That helped me out a lot when I first played CSE. You can add me as well, if you'd like and we can practice some. :D
