I spotted that too.
I noticed. I can see this causing a great deal of problems as it is a false indicator at some casinos. It will lead to players making a cash-in because all the signs are that WR has been met (bonus=0), but the casinos that are not EZBonus are simply adding the bonus as cash and expecting WR under the old system.
Just wait for those complaints to hit the forum when players have token refunds or winnings confiscated.
In general, it is an improvement on casinos that asked for 20x D+B on slots, but for casinos where WR were less this will be a bad thing. Worse for some casinos, it makes deposit related bonuses more attractive to players against winning chips in draws and tournaments.
Casinos affected could always change their bonuses using expected value mathematics and offer something suitable for the EZbonus system.
I would prefer this as, once working, the struggle with cut & paste and E-mails to CS will be a thing of the past. Another benefit is transparency, no more claims by CS that you "miscalculated" when you worked out the wagering, the software gives the cash-in balance, and simply won't permit any unearned bonus being cashed in.
I would hope that MG have enabled casinos to set their own multipliers and weightings as they do their promotions. This will encourage competition and not tie every one down to the same deals.
Anyone who wants to try this can go to Casino Action (Accredited zone above), although it has not been implemented at Challenge yet in terms of the new lobby. Any casino with Avalon etc. should have this extra.
