My 10 cents on this:
1: These are visual cues. Makes live a little easier, so...I support this suggestion
2: Why would you want this? My xxxx is better/larger then your xxxx?
I don't support this
3: Basketball is a Team game, so the whole team is to blame when an opponent scores. This goes for your suggestion no.2 as well, btw. Again, I don't support this.
4: Makes live easier. I think Arena price and attendance information is one way to get better intel then your competitors. If you're willing to spend more time by checking on their arena prices and attendence, you can get a feel for ther income. More info means better decisions. Posting the info in the Arena page would allow everyone to get this info easily. Are you sure you want to share all this info with your competitors? I don't support this suggestion
5: This would indeed benefit Playoff/Relegation Teams. But it would be a realistic change. I support it. Maybe we could offset the benefits a bit by allowing teams no longer participating to have scrimmages where the ticket sales are spread between both teams. The attendance would off course be not as high as with playoff games, but at least they would get some income (which would be realistic as well).
6: I support this totally
7: I support this one as well
