Whilst I agree with the defense for the corner kill, the kill on Volt and especially Ryo is enough for me to be sure Calidoso was using ESP. No amount of sound whoring can help you track people through walls like he did, especially when Ryo (Morgan) is going up those stairs.
Either way we'll have a proper discussion about this with multiple staff members available to give input, therefore I'm going to go ahead and say that anyone who wishes to give constructive feedback may, but I want it to stay civil and on topic.
