It will be interesting to a delay mode during combat when you don't want to use one characters in his initiativeposition for the turn and send it at the end of the intitiative line. also, can be good to waiting action like long distance shoot and the character just shoot with his long distance when someone movie in the range. Do the same thing with melee range and magic range. The wizard can use is free spell to cast in the people on range. So when one of you character can do nothing and you don't want to move it or you want to wait that someone come in your direction you can do it.

Now the only thing you can do it lose a turn for nothing.

Yeah, I also want these options.

Yes please!
