After getting a hold of the RoB and looking at the new vehicle rules a certain issue has cropped up concerning how certain skills are handled in the game.
These skills include Pilot, Scholastic lore, and some others that include the (any) option in the advance lists.
The clarification desired is: How are these skills treated? As all the other skills/talents or differently based on the (any). There isn't any specific description in the book hilighting how exactly the skills with the (any) option are treated.
The issue cropped up because I've been wanting to have my PC become pilot for our group. The Thunderhawk and Stormraven are both considered spacecraft but can operate as a flyer and a skimmer. The questions that we had was, does the pilot need one of the 3 skills to operate the craft in the associated mode, or does knowing how to pilot the crafts primary type allow the PC to use it in all modes? Piloting in space is vastly different than in an atmosphere as a flyer and the same goes for skimmers, each requiring their own training and skill-sets. While the T-hawk is a spacecraft it doesn't make much sense that a PC can fly one in atmo simply because he has the skill for the crafts primary type. The problem with needing all 3 skills is the pilot skill is only available once at rank 3.
If treated as all the other skill talents then when you select Pilot(any) at rank three you choose a single group and thats the only time you can buy one and thus the only skill group you can learn. The only thing (any) means is you get to choose the group. Thus a PC can only learn multiple piloting skills via elite advances.
On the other hand it would stand to reason a skill with the (any) option could mean you may choose any of the skill groups associated with that skill each one at the XP cost. I.e. at rank 3 you can choose "any" of the piloting skills each one costing the 800 XP (2400xp for all 3). This way would make sense common sense wise as all of the (any) skills are the type of skills one would expect to be trained on or learn via a training program. Scholastic Lore: classroom training, Pilot/drive: a few weeks training in classroom/simulator/actual craft, speak language: book study and practice, etc... Unlike skills like Forbidden lore: information you wouldn't find in your local library (first hand knowledge and the like) or talents you can't really learn more than once.
Personally I see no reason an Astartes is incapable of learning multiple languages or piloting skills, but if such is not meant to be, c'est la vie. It would, of course, be nice to have this cleared up.
And if he can take as many as he likes ('cause this no multiplier), why are there other Psychic Powers in later ranks? Then there are those call-out boxes that state you cannot Skills/Talents that you already have at Character Generation. Reading it the way you've done above, that would imply that you can take them again once you hit Rank 2! That doesn't make any sense either.
