I can see both points of view here. Bottom line is, MR is here to stay (at least for the foreseeable future). EF seems like the tyope of person who would go all-in at anything she is tasked with. It just so happens that Barry Hearn saw an opportunity with pool. There likely wasn't a long line of folks at MR willing to put their careers on the line for a struggling niche game/sport.
What a perfect opportunity for a young, intelligent, workaholic such as EF. If it succeeds, she has altered the course of pro pool and can stake a claim to being as you say the "queen of pool". If it fails, well it never really had a chance and she goes back to working on various other MR endeavors. I hope she succeeds, just to see what heights she can take pool to.
I also understand they are after complete brand domination. They want people to think MR and WNT anytime they think of pool, and this is where they may lose some of the tradition and pageantry of the game (like the silly purple 5 ball!)
DCC harkens back to Johnson City, a time of the road man, the man who needed to be good at multiple disciplines, men who proved their mettle by betting their own and putting the cash on the rail. This colorful part of pool is what I hope doesn't go away completely.
