If we only have 20/20 or the hundred then Cricket is fucked
Test Cricket needs the ODI 50-over game for development, batting proper and bowling 10 overs is key for test cricket.
Smash Ball cricket with little skill with bat or ball and it is Killing Cricket as a Sport.
If you want Entertainment then give 20/20 or the Hundred its own Governing body and split and Break away from Test and ODI Cricket and label it Fake Cricket
Am board of 50 over games rather watch a test match of 20/20
