After Easter, I used all my 21 explorers to search for adventures for several weeks, and do nothing else. The goal was to find scenarios.
Result: 411 adventures and 21 scenarios, before I gave up.
My goal was to complete the achievements "Find 100 scenarios through adventure search" and "Complete 1,000 scenarios". I'm currently at 21/100 and 17/1,000. I haven't found any "The Grain Conflict" or "Twins" at all.
At this rate, it will take a VERY long time to do 1,000 scenarios, if I'm about to find them myself first. Which probably is the only option, since they're extremely expensive the few times they appear at the TO. By finding them myself, I will get roughly 20,000 adventures before having all the scenarios...
I don't understand why these are so rare, considering the huge amount we have to complete for the achievement. To compare, the highest number for adventures achievement, is 100, and these are very easy to get. Someone said in-game that mini-adventures, like Easter event, will count for the achievement - I don't know about that, but it really doesn't help much.
Is this intended, or is BB intending to add many more scenarios, but haven't gotten there yet, or is there something else I am not aware of?
