In this week's game, my group chose to avoid mid-solo rolls by asking the LEAD to include a cost whenever they were overcoming an obstacle. We didn't put a lot of nuance into it and just left it up to the LEAD to decide how severe the cost was. It worked really well and kept the game flowing nicely.
Going forward though, I'm thinking about having the LEAD consider whether they were using their EDGE or a TRAIT at the time to give a better indication of how severe the cost should be.
Still having a blast! :)
