Is using voice chat considered standard for T6+? I'm not ready for T6 or above quite yet (only just cleared T5), though I've noticed groups appearing in PF. Most of them state that using TS or other voice programs is a requirement to participate in runs. I was wondering, how important is this? Does 2nd coil require a much higher degree of coordination and communication compared to earlier content? I was hoping I could get by without using any voice programs.
