You can't leave that line for Kosh, if for no other reason than by this time there are no more Vorlons left. Plus, the perception of the Vorlons as a whole is considerably different. Kosh my have been the exception, but with Crusade it was time to set itself apart from the original show a bit more.
I just thought that Galen saying the line was going over old ground, that was more interesting before. If Crusade wanted to set itself apart more it should have tried something different. It's only a small thing though...
Then again I rather enjoy a character who says "I have no surviving enemies. At all."![]()

Totally agree! I love Galen. An episode with Galen in makes it about 50% more interesting. Him, Dureena and Max were probably my favourites from the short run.
