Okay ... before today, I had my suspicions that the gear your followers have (visually) equipped changed based on their ilvl. Not all of them, and maybe just their weapons.
But, I had a belf pally I'd mostly left low level working my tailoring building. He used to have something like a spellfire longsword or a blade of wizardy, can't remember which exactly. Hell, maybe at different times he used them both.
But, today I went to finally get him up to 645 ilvl, and I noticed he's wielding Quel'Delar now. I may not remember exactly what he had before, but I am dead certain it was not Quel'Delar. I think his shield is different, too.
Anyway, I haven't seen anything about this anywhere. Anyone else noticed follower gear changing, or is my head playing tricks on me ?
