I had a problem I wanted to try and solve with running a large group of 6-7 players and it led me to this idea I thought could make a cool set of variant feats. Things take too long with so many players leaving people bored when they are waiting for me to get to them.
I know the commander is in playtest and dont want to step on their toes. This idea may not be for everyone and thats why its in the homebrew section.
Teamwork formations.
Integrate Watch - You team up with another character during exploration keeping an eye out as the other looks for clues/tracks or other activities. When an encounter begins the player with this feat rolls perception for initiative and both character act on that initiative result.
