Ah... yeah, well the ones we have rarely need any editing it seems 

none of the new terrains are part of it at all.
I agree, actually, with your assessment regarding field promotions. I don't believe they need the negatives at all.
Is it on purpose a Ballista Elephant cannot be promoted to City Raider V? I have both Combat 4 and City Raider 4, but CR5 simply doesn't show up as an option.
I've then added XP via the World Builder to that unit, but even with 1000xp the promotion never showed up.
It's working fine for the Assassins I'm using to harass my neighbours, but not for that Mounted/Archer hybrid Elephant (although the description of the promotion says it's available to both Mounted and Archers).

I believe those are simply by xml design.
I wanted to mention here... I'm doing some general debugging (well... focused on traits) and I noticed that Crusader is being removed from units that we may not want them removed on due to the fact that the promo increases looting, which will make it impossible for it to be placed on any unit that cannot pillage. The only problem with this is that Crusader also has a number of other benefits so it might be something y'all want to rethink... perhaps it shouldn't have the looting benefit.
There's nothing that's limiting them based on movement I don't think. I was saying I figured the issue on those units was how they were established in the xml. However, if City Raider V includes the Blitz ability in its profile, its going to be auto-filtered out against units that can only move 1 space so it really shouldn't be a part of City Raider V.
