Bracken, who triumphed on the ice dancing reality show in 2007, claimed that alterations to the voting methods and skills week were misjudged.
In the opening two weeks of the competition the eliminations were based purely on the public vote with the judges acting purely as advisers, while in week four it was up to the celebrity skaters to eliminate one of their rivals.
Writing in his Blue Room forum blog, the ex-rugby star said: "They were great ideas, however, all at the wrong time which is such a shame.
"Can you imagine if next week was purely down to the public vote or if the celebs got to decide who stays and who goes? It would make great TV. The twists would become so interesting. Would the celebs vote tactically? Would the public vote to keep the best skater Sam in?"
The sports star also claimed that the professional skaters on the show are not given enough air time or credit.
"The public don't get to see enough of the professionals and their CV," he said. "Strictly Come Dancing relies heavily on the professional to come up with the routine - that way we see so much more of the pro. On Dancing on Ice it is all down to Chris [Dean] and Jayne [Torvill].
"It would make a great twist one week for the pro to choose their song and choreograph their own routine... They deserve medals for what they have to do with the celebs."
Dancing On Ice continues on Sunday.
