All the WSOP events <= $1,000 have much less play this year.
With the new blind structure, the cost per round more than triples from level 2 to 3! It goes from 150 (50/100) to 475 (75/150 + 25 ante * 10 seats). Antes will start in level 3 already instead of level 5 from previous years. The four-figure event I played last year with over 4,000 players will probably be ITM in Day 1 this year,
instead of midway through Day 2.
For the $565-$1,000 NLHE events with 5,000 starting chips, which most recreational players will take their WSOP shot at, such as the Colossus, Ladies, Seniors, Tag Team and Casino Employees, this means that you are already in the Orange Zone by level 3 compared to level 5 before. The Patience Factor worsens from 30.5 to 21.1. The blind-off time (world's most patient player) worsens from 5.5 hours to 4.6.
