There is actually no need to keep the test format as an active format of cricket, to be honest. No one is interested in this format and the teams are also not interested in playing test cricket anymore. At the same time test cricket is not something with which cricket is going to spread throughout the world as well. So I think this cricket is just a waste of time. There is no reason for only four teams to keep playing a format of cricket that no one actually cares about anymore. I honestly don’t think that the people who actually loved test cricket truly, even they actually care about this cricket anymore.
Actually I agree with this argument. Test cricket generates only a fraction of the revenue when compared to ODI and T20I cricket. And it is competitive only when the pig-4 plays against each other (Ashes, BGT and Trans-Tasman Trophy are the ones that generate maximum interest). When other teams are involved, the matches are lop-sided and hardly anyone watches them. But the traditionalists want boards to give more importance to this format, and the teams to play more test matches. My opinion is that teams outside the pig-4 should not play more than 3-4 test matches per year.
