As the thread title - do you play with shared resources on or off, and why.
Personally, I've always played with shared resources on, just because it was the default setting. Having discovered exactly what it does, I tend to turn it off now because if one person doesn't cap his points, then the whole team doesn't suffer. If you need req/power, you can always ask for it, so that's not an issue. I think it just cuts down on the overall resources given to each team, which is a good thing IMO, because resource management becomes a big part of the game again.
