They could speed up the deal
This is my only gripe with it (apart from a couple of the presenters - none of them Blonde-related, obviously - whose manner would sometimes be better suited to Jackanory than a poker programme).
The deal is painfully slow - and there's no point to it other than as decoration. No-one's having to deal any cards, the computer knows what they are instantly - so why do you have to wait for them all to drift into place every hand? Just have the cards pop up, much as they did on Tribeca, and as you say, you'd get extra hands in without changing anything else.
I don't really see the point in complaining about the structure though - it is what it is, and it's not like there aren't any plenty of other tournaments out there to choose from.
I enjoy playing it occasionally - though I do need to check who's presenting first... Sometimes it can be brilliantly watchable, other times outright painful.
