They have said there will be a formation option coming. But until then if you have the teleporter pyramids you can use those to regroup your party. I think it only costs a couple AP to use and that gathers everyone on the lead (assuming your lead has the other pyramid).
I would like to think there will be an option to keep the Staff as well.
Splitting Arrow does need work. I also hope they add a Rain of Arrows skill. Arrow skills are underdeveloped as is. I would hope we could have skills that would be similar to the different types of arrows that can be bought/crafted.
