3. The whole archetype system. The characters are Acolytes for the Inquisition. Being limited in what you can learn by your carreer seems a little problematic. For example, if you play Cleric for an Ordo Xenos Inquisitor, you simply can't get the Xenos Lore skills except as Elite advances which doesn't make a lot of sense. There should be some skill blocks that should be made available to a character based on who they work for and what experiences they gain during their time working for the Inquisition.
That does depend on how you approach things. The way I've been running it since the playtest finished was that the Career Path basically covered the stuff that a character is naturally more inclined towards, the things that they're regularly training to be better at, and so forth - it doesn't take them anything special or extra beyond the XP cost to buy from their advance scheme.
Elite advances are, however, available to everyone, so long as the opportunity is there, and the inclination exists to take advantage of it. Anyone can attempt to learn anything (within the restrictions of prerequisites), so long as they've got the time and effort to devote to learning, and the means to learn it (it's difficult to learn about Xenos if you're on a feral world with no Xenos species, no research materials, and nobody to teach you). It's not something special, so much as something that requires a little extra effort on the part of the character.
I agree with you to a point, N0-1. But using the example of a Cleric working for Ordo Xenos, you are being exposed to Aliens in various investigations. So why should the Cleric have to spend 200+ experience on Forbidden Lore (Xenos)? It would seem they would either pick it up as they continue to gain exposure, or at least be able to purchase it for only 100 experience since they have had the exposure and will naturally try to learn more about it since it is what they are up against most of the time. Remember the description just says "knowledge of the most commonly encountered". It still doesn't cover the more obscure.
Or take an Assassin who needs to go incognito as a Noble for a mission (as in Scourge the Heretic) there should be a way for them to get a crash course from someone else to get the basics of Charm and how to interact in these settings. There are several horror stories in the old forums about DH sessions gone wrong because of the group make up and not having the skills needed because of the carreers.
Or how do you pull off an investigation if no one has the Silent Move, Shadowing, or Inquiry skills. Does it make sense that you have to pay twice as much as the skill would normally costs just because it isn't in you're career path but because of the nature of the game, someone really needs to have those skills?
This is why I think there should be blocks of skills laid out for each Experience Level that are based on the nature of the game. You have an Ordo Xenos game geared more towards investigation, then at Level 2, maybe you make Inquiry available to everyone at 100. At Level 3, maybe you make Silent Move and Shadowing available to everyone at 100. At Level 4, maybe make Forbidden Lore (Xenos) available at 100. At Level 5, how about Tracking at 100. At Level 6, Disguise at 100. Level 7, Forbidden Lore (Xenos) +10 at 100. And At Level 8, Forbidden Lore (Xenos) +20 at 100. Maybe throw Charm or Interrogation in there somewhere if it is appropriate to the game pace. Not talking big changes, just making the skills they need to do the job more readily available.
These aren't big changes, and not everyone would buy the extra skills anyway. Some people just don't see their character going in that direction. Some people would jump at the chance to help the team.
I see the Elite Advances more as a way to purchase skills that are out of your carreer path that would be nice or helpful, but not critical to do the job. Unlike the example listed above which I see more as skill critical to doing the job an Ordo Xenos investigation based team.
Does that help explain my thinking?
