I don't have a problem with a 2 stat. I will often try to deliberately engineer a 2 for every character, just to represent a weakness, and to make them more interesting. Most recently I did this with with Charisma for my Orc Sam, as my co-players are all new to the game and I thought a nice stereotype would be fun. Somehow he always ends up being the one to do the negotiations, with hilarious results. Dump stats can be fun!
I agree with Glaive. I am really hating limits. I see no reason for them at all. There are already upward limits in place, ie dice pools. Unless you pay Edge, you can't ever roll more hits than your dice pool. Most people won't be tossing 18 or 24 dice for more than one or maybe two skills, so I don't see huge numbers of success being a problem. And those one or two skills where you CAN get six or eight success on an average roll, well, shadowrunnes are extraordinary folk, with military grade implants or magical powers that SHOULD allow for results well beyond what a normal human can achieve. They re not ordinary people and should not be held to ordinary successes.
And yes, you are likely going to see me rant about this regularly, until I have a copy of 5th Ed in my hands, and suddenly fall madly in love with the idea(aint gona happen).
