I play on both William Hill and Betfair
and the last couple of weeks their software has been terrible, freezing and crashing all the time.
I have been playing on William Hill's site for many years and while I agree
that it has changed, not in the players' interest, but then I think all sites have changed for the worst in the last few years.
Just try getting a rakeback deal these days, they are very rare, years ago every site, apart from PS of course, had rakeback but not now, it's all rubbish VIP programmes now.
