I'm not saying reduce run speed to the point there's no point/advantage speccing more run speed that someone else, but it should be more balanced (flatter run speed increase curve per points spent or something), so that speccing CON is also viable.
For Spies and APU's runspeed was usually always more important than CON, but that's because they are meant to be squishie.
The whole aiming thing seems strange since NC1/NC2. I would prefer that people can hit the cap again and then it is down to other factors how well they fair. Their aiming skill, damage, movements, weapon characteristics etc, etc...
