Yeah, it is very important that the narrative impact be appreciated and rewarding. This isn't just the Elf rolls Awareness and the LM answers 'the distant folk are Riders of Rohan' but that the 'the distant folk are Riders of Rohan, 105 in total, with three horses that are riderless, being guided by others. Their spears are very bright but their shields are battered, as if they have recently been in battle. Their leader is very tall. Almost all of them are blond-haired and, though it's hard to tell from here, grim-faced.' That gives a lot more detail, and, more importantly, provides some excellent hints about how a Council might proceed and what questions to ask.
If you have to put a numerical value to it, consider it worth at least one more Tengwar.
Maybe it's meant to be the new Deadly Archery, spawning 50+ page forum threads....
That was definitely not my intent.
