TS for me is a sweaty chore, I'm deaf and have to have all my levels turned up to max, My headphones, my hearing aid, and the personal TS volumes have to be set at their highest, I can hear if people have good mics and don't talk over each other, but when it becomes a clamour and people are just shouting out random instructions I'm lost.
TS/Discord must be a supplement to typed instructions in a battle to be fair to all. Raxius used to type headings for me and others in PB's.
As for organisation, nominate an experienced PvPer if there is one at the time, if not then ask for a volunteer and follow their instructions.
