There would be some overall benefit (I think) to raising the buy-in for the Main Event to around $20k. Inflation is just one reason. Second is that it would pre-eliminate some of the lotto players. Getting 'lucky' once doesn't entitle anyone in any other sport to a Forever World Class Player status. Just makes them another World Class Luckbox at the Main Event.
History of poker has been, in the past, for reasonably skilled players to win and with luck being an added factor. It has gone half-circle and now favors Lady Luck.
In my own observation, watching the true pros at the WSOP, they seem to have lost interest in playing the Main Event. Focus has turned to encouraging more support for the HORSE Event becoming the master prize. Many luckbox players shy from entry into the $50k buy-in, or it would already be a larger event.
Sure, the pros play to win, like anyone else in the Main Event, but you can tell the excitement is gone for them. They enter because it is nearly 'required' for photo opps and endorsements, NOT for the sake of playing quality poker. If they want quality, as they exposed in many interviews, they prefer the high stakes cash games now.
Other comments made earlier about year-long events, rankings, etc should be considered. Yes, WSOP has Player of the Year, but it has no relationship to the Main Event - but it should in some manner.
If it is going to grow as a Donkville Event, drop the buy-in to $3-5k and move the Main Event to the Vegas Convention Center - and may the best luckbox win. A live
