Yes i agree. It will make the event boring and will definately have an impact on the ICC cricket calender. Moreover this will only let the BCCI to grow financially and i am sure ICC will have an uneasy feeling about it. they will do something to curb it down to as short as possible. Personally i too don't want it to be too lengthy. It was fine if they had this type of system for ODIs, but for t20's they should keep it short and simple
