They spoke about abandoning the toss a few years back but decided to leave it for now.
There has been growing concern that home boards have manipulated conditions to suit their team, in turn adding a disproportionate level of importance to the toss

I like the idea of removing the coin toss to a degree but it's not very good if the touring team is a much stronger team than the hosts and you get another walk over but for the visiting team rather than the hosts.
I think there should be another rule added where if the touring team is 3 or more places above the home team in the world rankings then it should go back to a coin toss.
A bit messy...
