No such thing as a touch attack in C&C I'm afraid. However, since the CK is running the show it stands to reason that such attacks will exist whithin the game. For instance an attack with a molotov coctail (easily concoted) would be a "ranged touch attack" with or without the actual term. It's all up to the CK. Another example: There are rust monsters in C&C and few would argue that armor protects against the antennae-attacks of such a creature. It's pretty self-explanatory as most of the C&C rules. The CK has to make a lot of decisions in that rules set.
Oh, and my house rules weren't deviced to fix anything. C&C works fine as it is - I just want to flesh out the combat system a bit.
