Really annoyed with how GC handles things

My friend was telling me that there was an interview where the interviewer claimed "warriors are too good against casters right now, having too many interrupts amongst other things."

All GC said in his response apparently was "There was a bug with diminishing returns on charge."

If this is true, and this was his only response, then he is really pathetic. I am not saying warriors are op, underpowered, or even that the interviewer is right, but a response like that is really, really pathetic.
