We heard for a long time in CoX that skill sets were on the way. I think they could have been employed as either part of enhancements, or as part of Alter Egos. Sometimes, your attempts to do something to assist others will help improve your skill at solving a problem.
These items would trigger much more extrapolation from your character in chat-with-Contact scripts. The more skills you have in a situation, your rewards also marginally buffer, but the real rewards come in the scripts come alive and your character is much more active in his missions, relying less on others to solve problems. In a group situation, everyone's skills work, and different characters respond to NPC dialogue differently.
A big example of this in CoX would be Atta's bombs. Disarming them would be something a player is given instructions for by an NPC-- so they are only reproducing the work from instructions, there is no talent required. Completing that mission would automatically grant one point of Bomb Disarmament. In any situation where the character encounters a bomb and wants to turn off the timer, the character is +1 to diffuse the bomb when a success is tested. (This means characters could potentially clear a Landmine field set by a blaster whilst stealthed... although it might come off as a bit obvious that someone's done a disarming, and if it fails, OUCH.)
There would be an optional mission after walking out of the mission door, to retrieve the bombs for study. Bomb Retrieval skill +1 if successful (but there would be a spawned attack and the potential to have the bomb go off on you). If successful, you receive an inspiration that can immediately creates a bomb as an object.
What I'd like to see is stuff like this. (I got started on this list and two hours later I'm still coming up with ideas)
Academics (General) - A general category of catch-all, that makes your character less of a specialist, more of a pub quiz expert. All the really left-field information and trivial stuff, your character knows.
Academics (Mutation) - knowledge of Mutant backgrounds; recognize genetic traits
Academics (Occult) - knowledge of Occult backgrounds; recognize occult symbols
Academics (Science) - knowledge of Science backgrounds; recognize chemicals
Bomb Disarmament - ability to disarm various bomb types in the game and in PvP
Bomb Retrieval - ability to collect disarmed bombs in the game
First Aid - knowledge of healing; Bonus to Natural Healing
Medical, Basic - understand what goes on in a hospital like a qualified nurse, bonus to disease
Medical, Intermediate - understand what goes on in a hospital like anatheisologist, bonus to anti-Pain
Medical, Advanced - understand what goes on in in a hospital like a general practitioner, bonus to heal blunt, edged damaged
Medical, Surgeon - understand what goes on in a hospital like a qualified surgeon, bonus to heal fire, toxic, radiation, etc.
Streetwise - have all sorts of insider knowledge of crime and gang life
Veterinary Medic, Dogs/Cats - bonus to heal Dogs & Cats
Veterinary Medic, Birds - bonus to heal birds
This would also allow for the automatic gain of combined talents, when applicable:
Medical, Advanced + Academic, Science = you know lots about Nanotech technology (Bonus to Device Healing)
Bomb Disarmament + Bomb Retrieval + Stealth = you know about Ambush Bombs (chance to spot ambush bombs)
Streetwise + First Aid = Triage (Bonus to Natural Healing powers)
