Graves

I've been playing Graves for a while now. Just bought him and he is great. I've encountered something rather questionable tho. Seems that every now and then one of his auto attacks from his shot gun turn into blanks. I hear the shooting I see the animation, but the bullets wont come out and champion/enemy don't get hurt. This highly affects graves gameplay since he has 2 shots and then has a reload time.

Thank you very much for looking this over and if anyone has experienced this as well I'm sorry and I feel your pain.

I hope I got this thread right. Im new to using forums.
