I witnessed the situation twice that a coach went to vacation, set up his team, got a player injured in the first game and had a whole mess in shapes and results when he came back. Both players lost their solid chances for competing in the playoffs, entering 2nd and 3rd overall they saw their teams down to 3 players in shape when it mattered.
Of course you can setup your lineup in advance, but honestly, such a limited access will not really change much for the negative, while it opens up alot to the positive.
