The fewer players you have, the more need to change roles.Last night I played 2p with my mother. She was the generalist the whole game. I started as the rescue specialist.
I changed to driver, captain, driver, specialist over the course of the game.
We won the game with no hot spots left, two hazmats on the board, one damage counter in reserve and about 25% of the building on fire.
EDIT: I also recommend random role distribution to encourage more role changes. You really don't know what to expect when rolling up to a fire, you should emulate that in setup.
