I had to open a new one as a continuation of this one, because there were no replies at all.

So, tobei/daiske, the official reply here is that the chance for expert mode to drop 1 advanced thread is so low none in six weeks had the luck to get one in a feature that in 3.0 in china dropped them with a 50% chance per try with a number of 1-3 per time.

This means you are actually telling us that oasis choice - in complete opposition with tencent choice with 3.0 - is, basically, to not grant any realistic chance at all for their f2p or low cashers players to reach rank 7 battle armor during their common playtime since requires 700-800 advanced threads and with the odds you are prospecting us in extreme mode sa not even in 25 years of tries we could hope to get the threads we can't get from the spacetime shop.
