Hmm, I have to wonder how big a role NPC's will have in the real event, since I'm thinking it might be better not to participate in the real thing (or I'd have the perfect deck ready for each NPC I get to face :p).
You make a good point, that applies to most other potential WoE jobs. Those who volunteer to help organize the event will often have "insider" information that could grant an advantage. How will we deal with that? The easiest solution would be to have organizers not participate in the event, but it'd be nice if we didn't have to do that, since organizers who are actually playing in the event will often be more motivated to go the extra mile in their duties because they are that much more interested in the event.
Goal is to make most staff titles so that they do not prevent you from participating in the event. When organizers can participate themselves, they are much more motivated, like torb already said. But NPC staff position is a bit tricky because they will know the decks. I'm not sure what to do about that.
I remember it being said that NPCs have a set 'theme' and slightly vary on their decks. I recommend sticking with that sort of thing. Let's take Bala, for example.
His theme, are the elements that were considered 'weak' right? So I might go to play as Bala, against TerrorKing, and use a
![Water :water](https://elementscommunity.org/forum/Smileys/solosmileys/../../../images/Misc/water18x18.png)
deck. HOWEVER! The next NPC player, let's say Napalm, might be used to play Bala, and she might do a
![Life :life](https://elementscommunity.org/forum/Smileys/solosmileys/../../../images/Misc/life18x18.png)
rush against Kirch. If we go on a theme-basis, we can keep the NPCs interesting, and less 'this is how you beat X' which is something that plauges the FGs. That said, perhaps NPCs should have a set 'weakness' in that they will never have a plan for X type of card, so Bala, might always be vulnerable to CC, while Dumbnar will never use spells, and so on and so forth.
