don't know, if this is the right sub forum for this suggestion, but this idea just plopped into my head while thinking about that noticeability problem concerning legendary drops.
So, I'd really like it, if the followers would get some text to say -hope the artists are available. They work pretty well as an elite-radar and the Templar saying "Oh my god, look at that sword over there." would be pretty nice. You'd have to replace sword with something more generic probably and NOT use the exact same words he uses on monsters(though it would match his character :P), but it'd still be a nice feat imo.
I would prefer something more obvious, something more like the achievement pop-ups. But that might end up to annoying again.
It could only be part of the solution anyway because it'd be single player exclusive
I'm no expert for visual solutions though, but the item text should probably do, just give them a better color and not ugly orange. Blue and yellow items kind of shine even when the text already disappeared. That dark, brownish orange is just garbage.
The Best way to see a Legendary is to make it Show on the Map in Orange on the Mini map and on the Large map.
But a text popping saying a Legendary dropped it's cool too but if u can't find it - not cool
