This is another one of those tongue-in-cheek posts that should be
prefaced with a disclaimer, right? 
I'll venture that there are damned few players that attend Dancer's
classes who subsequently prove to be losing prospects for the casino.
(Or do you think he strong arms casinos into paying for the classes? :).
The classes successfully bring in new players to the casino who, in
turn, are likely to play a good deal of games with a strong hold as
they are to direct some play to better games with weaker hold.
Concerning his consulting services, while admittedly they work against
the interests of players looking to "suckle off the tit" of the
casino, I'll venture that Joe average benefits. It's apparent the
many casinos have difficulty inventorying strong games in a profitable
manner. While the games provide an adequate hold under standard
circumstances, particularly when they attract active play, occasional
promotions prove to be the casinos' undoing when droves of skilled
players flock to the casino to take advantage fairly strong EV
opportunities.
The consequence is that once a slot manager has been bitten hard a
couple of times they become paranoid. They have little interest in
exposing themselves to continued risk with the inevitable consequence
of a "slash and burn" of good games.

Contrary to what some believe, Dancer doesn't advise casinos on how to
best bleed players. Rather, there's good indication that a
consequence of his services is to educate casinos on how to offer the
stronger games that attract more savvy players while limiting exposure
during promotions otherwise intended entice larger players base
profitably.
I can't speak to the greater universe of casinos, but I believe Dancer
has played a part in Borgata's initial introduction of Jacks to AC at
a time when there was a dearth of good plays in the city. In the
ensuing months and years other AC casinos have inventories respectable
Jacks (and other game) inventories where there had been none before --
likely reflecting both an effort to stay competitive and a new
expectation that what's good for Borgata (with the highest overhead of
any AC casino) could be good for them.
This is a dramatic turnaround for AC. Admittedly in the last year or
so cashback and promotional opportunities have weakened in AC. Still,
Jacks inventories have remained respectable (though perhaps a little
thinner of late) giving the informed recreational player a shot at
near-even odds play (akin to that enjoyed by blackjack players at some
casinos).
