The numbers I've seen thrown around that caused the caps to be implemented don't seem to me to show up except at the peak peak times, like Friday night, Saturday, and TT. Even then, it's generally in the 300 and change area, if I remember right.
Maybe I'm wrong, but it seems to me that having an arena full of people to fight where you feel like just one in a crowd is less of a turn off compared to having an arena that feels empty when you log in.
I'd be very curious to see what it would be like if they just did like Kazaa suggests. The people looking for the crowd could find it in Orange, and the people looking for smaller fights could also find it in Blue.
The problem with this kind of spitballing is, the detrimental effects (if any) wouldn't be seen for a while and they'd probably be subtle. For the first while, numbers would be up, constant threads on the forums trumpeting how awesome it is that they did away with caps, etc and soforth. The test would be what the game and peoples attitudes looked like after 2 or 3 months.
Lusche- Just throwing this out there as a caution, but might a play style shift skew the kills/tour numbers a bit? Just as an example, if the majority were more inclined at some point to luftberry til they were dead versus extend and rtb tactics being more popular at another time that might skew the numbers some, wouldn't it?
Still, it should be a decent enough baseline I'd think.
