Well now theres probably 10-15 teams on final coils, thats a close guess i think, we had our server first T13 clear 2 or 3 weeks back, a second team just cleared either this week or last week with 4 more teams on t13 progression.
My own static plus 3 or 4 more are progressing t12, the rest are most likely stuck on 10. So you're only looking at a handful of people in the latest coils
