Sometimes it's better to Force a Fight over Baron/Dragon instead of taking it.

Sometimes my team chooses to rush baron, and I tell them to wait until the enemy shows up and fight them. But no, it's baron followed by a recall.

Situationally, forcing a fight with the enemy team can close out the game.

Say they're behind or have bad teamfighting champions and trying to stall the game. If we get baron, it's still the same thing. They clear the wave and continue to stall. Drawing them to a fight at baron will force them to show up and fight, meaning you can hit them with their weakness by forcing a fight.

This isn't always the better choice, but sometimes it's better to do it this way.
