Wasn't aware a change had been enshrined in law but am aware that umpires after a switch hit interpret that line of leg and off stump have interchanged as the change in stance is made. That make things pretty unfair on the bowler imo.LBW Rules have been changed to counter switch hitting so cant see your argument on that one. Bar 20/20 how is the balance not even, you only have to see the World cup to show its balanced and how times have england scored 400+ in the last few years at test match level? and the county championship which is as bowler friendly game as it comes. I guarantee batsman would be lucky to hit a Century a season and local games would be a mockery. Genuinely not sure people are truely watching the game or play it to see that this is a crazy idea
Ball tracking evidence since 2006 suggests that if the rule was adopted average scores would change from 320 to 267 and a fall of wicket every 51 balls compared to 61 previously -hardly a drastic change. The new figures compare to stats when wickets were uncovered and certainly centuries were plentiful then in 1st class cricket. They were less in club cricket but certainly not rare but on the plus side draws in time cricket were far less likely.
The suggestion incidentally comes from Ian Chappell -I believe he's been truly involved playing or watching at a high level for 50+ years.
