I think this episode is an excellent episode. We get major events like the death of the Centauri Emperor, the assassination of the Prime Minister, Londo and Refa plotting to get closer to controlling the throne, Londo calling on Morden to attack the Narn, Londo's dream in which he sees his death being shown in full, the Narn declaring war against the Centauri in response to the attack, the introduction of the Rangers, and the declaration from Kosh that it will all end in fire.
Very nice.
