Retainers, too much interaction?

[Moonlite]

It takes 5 secs with the current system if that is too long you are in too big of a hurry

It has to be longer then 5 seconds. I can't quick venture all retainers if I am on the first and a duty pops at the 6th one I always fail to reventure. I have everything set up to make it as fast as possible for reventure.
