Well...I already have Exploit at rating 3, so I'm not sure why you think I don't already have it.
Secondly, dropping Purge would only free up 500 Y, which would give me 800 Y to play with. I could add Optimization 1 to 8 programs, but that isn't nearly enough cash to get up to rating 6 on Exploit. I'm already flat-busted with maxing out everything else that's been stated I need to max out on this character, so I'm not sure where to find the creds for this.
However, with that said, I did remove Purge, so I now have 800 Y to play with. I added Optimization 1 to Exploit, but now I'm toying around with adding Mute 1 to Attack. Is this a good idea to do?
