A bit of archeology, but to hell with that.
The biggest problem with Amber we've ever had lies in Attributes and vague description of fields they are supposed to encompass.
"Were I to know that Attribute x is responsible for y, I'd bet on different Attribute". "Huh? I did it, because I was sure it's gonna be WARFARE contest." And so on, and so forth...
To deal with this "problem", we tried to simply replace Attributes with some other, more intuitive names, expand their quantity, etc. Sometimes it was Body-Mind-Soul-Conflict, sometimes Strength:raw - Strength:finesse, all in an attempt to make the list more approachable. Results were mixed, no matter what we didn't manage to avoid occasional "are you sure Attr x is best suited for this task?" discussions, still I think the experiment was fun.
Recently, I had the opportunity to participate in a game running "Lords of Gossamer". Same thing happened when one of players declared short string of actions relying on his character's perception and there was a disagreement regarding matching Attribute. We settled for Warfare (as usual), but I think somebody's gonna suggest a slight change in upcoming games.
...providing we're gonna play. The only people interested with this kind of game are usually too busy, to meet often.
Anyway. I think the problem lies in language difference and different (perhaps cultural?) understanding of certain terms and corresponding activities.
Come to think about it, I wonder what Attributes "Olympians" use.
