I've come around the last week on edge decking, and I kind of like the RCC and comlink solutions for cheaper alternatives for decks. Getting a real deck is for the big timers.
My assessment:
1) Yes that one limit would really hurt, making edge very important.
2) When I suggested that, I wasn't even thinking of the possibility of a standard comlink having the ability to run sleaze or attack actions, since it doesn't have the software/hardware to do this. My first opinion called it "ridiculous", but to be honest, I've come around on this, because I really think that allowing that solves the gap now, and adds to the game. I'll be allowing that.
Note: By the way, I went to the big man himself yesterday to get his opinion on edge decking with a comlink. He said the system definitely was not designed to allow it, but that is was kind of a cool if unintended idea. That was good enough for me, and I'll be allowing it in our group when I take over GM duties next week.
