Gurgox got muted last night

We where running VL and when the time came to fight Gurgox we started and suddenly we all got wiped. No sound for none and then we went again two of us where hearing the growl but not the others we would have beaten him but a warrior decided it was better for him to take the green orb instead of me that could revive him and with less than 5% of Gurgs health he wiped the group. We tried it 4 times but he was mute and don't tell me to see his feet for red dust because on a phone its almost impossible to see that with all the casting. Who knows maybe its the Christmas cold and he has a severe cold but it is annoying.

Give us a visual confirmation of his growl like a bubble above his head or on the chat maybe he can change color instead of the red dust he could turn red (heck maybe even green like the hulk) but something in case this happens again.
