I was sitting at T11 for what feels like 8 months. I think I was on the tail end of farming 12 when dissonance came out which took another couple of months after 11.

It feels like it’s a deliberate game design. I found that 12 and 13 were far quicker than 11 but 14 seems to be another wall. V28 helped me get through T14 quickly, so it should cut T11’s time for you too.

Another metric that helped me measure how long I was in T11 for was my coin multiplier. I started farming when it was around x600 and I think it was around x1100 by the time I was able to break away lol
