I am categorically opposed to any rule which could result in a team's turn being skipped.
An effective turn timer of 24 will most likely have that result. IMO the absolute minimum is an effective timer of 48, and I'm tempted to up it to 72.
Why? this is a team game, surely the best team should win and this means the team who can best play as a team and not the team that can sustain the interest of members during exorbitantly long turn times, these long turn times are only killing interest especially depending on the map there could be literally nothing to do for a period of time!
The reason why I have suggested the change is that currently there is no reason why turns should take any longer than 24 hours for the immediate future of the game, there is nothing that needs to be polled on a turn by turn basis.
