Alignment weapon fusions vs Dragons

[Kishmo]

I had a character with a holy weapon go up against a dragon the other day. It was pretty great - fighting dragons is such an exciting, iconic, part of the genre, and it was challenging enough that true death was a possibility! But it came up afterwards that the only reason my holy weapon was effective against the dragon was not the dragon's DR being /good, but rather it being /magic, and thus overcome by any fusion.

I did a bit of investigating after that - the various alignment weapon fusions let you overcome DR/their alignment, and ignore the energy resistances of a set of creatures that alignment frequently opposes. But here's the thing - as far as I can tell, none of them give you any advantage against dragons. I checked all of the dragons and dragon templates I could find in the Alien Archives, and none of them have DR other than /magic, and none of them have energy resistances - only energy immunities.

So, as written, if you're hoping to be a dragonslayer, there doesn't seem to be any benefit to having an aligned weapon fusion, despite the dragon creature type being called out specifically in each alignment fusion. It suggests to me that the intent is for these weapons to be more effective against dragons, but mechanically there's nothing there.

Am I missing something? Should the alignment fusions overcome immunities for dragons? Maybe this is just to overcome the occasional dragon that happens to have resistance from an item, spell, feat, etc? Or if future dragons are published that do have resistances?

EDIT: Owen specifically confirmed that the holy fusion does not overcome immunities in another thread. That one didn't touch on this "should these fusions give some advantage vs dragons?" question, but still pretty definitive.

RAW no

RAI that is REALLY misleading having dragons on there.

Well, it helps when the dragon uses armor mods or spells to protect against the energy it's weak to. Or, I suppose, in combination with a biohacker turning immunity into resistance. That's abut all I have for uses cases.

I think the issue is that, just because a fusion overcomes a given type of DR in a given type of opponent, does not obligate said opponent type to *have* that DR. So, if you encounter a stronger, nastier type of dragon which has DR 30/Good, its useful. Or DR 30/-.
