I originally was playing around with a SURGE'd Gnome that could get to 9 Logic (with exceptional Attribute), but it ended up being really expensive on the Karma. The main thing I found when making this was that I spent a good 50-70% of Karma on Attributes, and 30-50% on Skills. Which is a problem. So, I needed to tone it down from the Priorities that I'm used to.
Honestly, a higher Charisma does not do much for me. Attack 2 vs. Attack 3 is such a small difference, that it doesn't really matter. The extra die is also not that amazing, and you don't get free contact points.
Software is staying where it is, because Resonance Spike is my only real offensive Matrix action. Compiling and Registering could use some love, it's true, but I'm not exactly sure where to find the Karma for it.
