Will one be able to save and load different formations, making one’s own preset formations?
We feel like we cant put anymore work/time into the UI for now. So probably not.
So there will be 17 reserve slots?
There are 9 slots for reserve (the tents).
Thus will it be theoretically possible to have 18 mercs in your party but send for example only that one Swordmaster into the fight against a pack of direwolves to level him faster?
Yes, as long as you have 10 or less guys (1 in combat and 9 in reserve).
