WI: Gaius Cassius Longinus killed at Carrhae

[Night Gaul]

At the Battle of Carrhae, Marcus Licinius Crassus suffered a catastrophic defeat at the hands of the Parthian general known to history as Surena. Crassus lost most of his army, his son Publius, and his life. The survivors of the battle limped back to Roman Syria under the command of Gaius Cassius Longinus, who would later play a key role in the conspiracy to assassinate Julius Caesar in 44 BCE.

What if Longinus had also been killed at Carrhae?

I recall Cassius helped defend Syria from the Parthian counterattack, so you may see some serious changes pretty quickly.
