I must admit I wasn't playing too much Missions when the FAQ was first started so please excuse if some of these topics were discussed to death already.
1.) Though mystic adepts must split their Magic between Magic-based skills and adept powers, it says that for all other purposes, including the limits of adept powers, the mystic adept uses his full Magic attribute. Does this mean that a mystic adept with Magic 6 who has allocated 2 points to Magic skills and 4 points to adept powers can cast Force 6 spells without flinching?
SR4A (p.195) and the official FAQ question stated above have conflicting answers. The Missions FAQ as written doesn't make it clear which ruling prevails.
2.) How do I learn Complex Forms between adventures?
Much like spells and skills, learning complex forms (SR4A p.140) is quite hard when one has to buy hits. Should complex forms have learning rules much like spells and skills (one free learning between missions)?
3.) How does a mundane use infiltration against astral observers?
Is it an opposed infiltration versus assessing test? Or is a mere success test for the astral observer? The Official FAQ covers astral on astral perceiving stealth but not mundane on astral stealth. I wish I had pages to reference, but this is a very not touched upon issue rulewise.
4.) Are the rules from "Incorporating Critters in Your Game" (Running Wild p.32-40) allowed?
I'm not sure if these are optional rules or not. I thoguht they were, but I saw critters used as rewards in Season 3.
5.) Are PDF Only books allowed?
While it's fairly clear that the SR Options line is optional and thus not allowed, what about books like This Old Drone, Digital Grimoire, and MilSpecTech? It seems like these books will become more common as time goes on so making it clear would be nice.
I have some questions related to War!. So here there are:
1.) What "Battlefield Skills" rules from War! (p.136-145) are allowed?
There's a lot of new rules in here and it'll be nice to know which if any are used in Missions.
2.) Can I purchase Military Grade programs (War! p. 144, 162)? And if so, do they degrade?
If they do exist for missions, do they degrade or are they covered by the Unwired SRM4 FAQ?
3.) What skill do you use for Battle Rifles (War! p. 154-155)?
Technically they use the Exotic Weapon (Battle Rifles) skill right now. That seems like an error. It's arguable that they should be used with either Automatics, Longarms, or Heavy Weapons.
4.) Can I use MRSI software (War! p. 162)?
This software is quite unusual. Is it allowed in Missions play?
Edit-
I realized I had one more.
1.) I have a rules question that is not covered in the Official FAQ or SRM FAQ. Where can I get an answer?
While I'm not sure you don't want to be "Rules Guy" for SRM, it'll be nice to have some sort of third party to settle rules debate especially when the GM himself is unsure how to rule.
