I've been poking around trying to find some answers to my many questions, since the wiki is down I have to do what I can.
I'm finding a lot of contradictory responses on some issues. No doubt because the game is actually quite complex but probably also because it seems that it's patches really change the gameplay based on user imput (which is great).
I've also been trying to catch up on the Banks vs Soundoff AAR, and while that helps a lot with understanding how veteran players plan things out it still leaves most newbies with a lot of doubts, at least I have tons

So here are two of them (and a hidden one):
1- In most scenarios at the start you'll have Medics and the Signal guys (or ballons) attached to Armies. From the tooltip it seems to me that they would be much more usefull if attached to the actual Corps or the Division that holds most of the men. Is this true? Is there a "nuance" I'm not seeing? Is there a good reason to leave them attached to the army when the army itself is just the HQ? ( On that note...I've read somewhere that Armies should be left alone with just the general and his HQ behind the lines of Corps that will fight. Is this true? What's really involved behind the thinking?)
2- In the Banks vs Soundoff AAR it seems to me that they almost always leave their armies outside cities. Now from lurking around I had understood that inside cities the frontage of the army is smaller so it would benefit the defender to stay inside when the attacker is stronger to be able to fight less units at a time? Is this correct? So why leave them outside? I can understand that if you are defending in force it is better to stay outside so you can defend with more units. Is this correct? But in the AAR one of them has said (i believe it was Soundoff) that being caught inside a city is, and I quote, "a pig"


Thanks in advance!
