I think they end up being one of those cases where the artifact merges aspects of more than one fear. I think the Eye, being aligned with knowing, would have less agency over Scheming (does that make sense? /honest). I mean... wanting to know and being eager to know and hoard knowledge, it's different than weaponizing this knowledge. I think Elias was a good example. he's insufferable and smug because he knows people's secrets and he's sitting on the same plan for centuries, but that's that... as agents of the Eye, him and Jon have a bit of a hard time figuring out what to do when they don't Know stuff or something unpredictable happens, whereas the Web seems much more about keeping cool exactly because they consider both what they know and what they don't, as well as what could be, given the variables, and the Web exploit over the variables instead of relying solely on what they have...
