@Michael Ernst- there are two parts to treasure dilution. Adding more people able to draw the max loot isn’t a factor. Not sure which one you may be referring to:
1. As the max loot that can be drawn increases, it becomes more rewarding to play. With people paying $4 per TC, a max of 21 TC per game, and a ticket price of $78, (only 58 at the smaller cons) we finally got to the point where a player can reliably make a profit by playing. “Farmers” can buy as many tickets as they want just for the loot, That squeezes out newbies and others who can’t turn a profit. The only remedy is to raise ticket prices, or cap treasure, or make each treasure worth less (change the percentages of uncommons and “good stuff” and as Harlax said, that’s already happening. It’s just math and simple economics.
2. Adding to that, someone suggested a TE that lets you filter the treasure. (Draw extra, keep the good stuff and dump the uncommons back in the box.) That would increase the percentage of uncommons for those who draw after. If enough people did that, you could theoretically end up with a loot box full of nothing but junk, with all the good stuff gone. The effect is diluting the treasure for people who don’t have the treasure filter tokens, and even those who do but draw later, with a higher chance of pulling other’s rejects.
