Nothing like selective evidence.
Yes, that picture is selective evidence. Unfortunately, for a lot of us it's what we experience every day.
Let me phrase it in an admittedly very polemic way:
When I joined AH, I was able to play with 200-300 players on a map each evening. Now it's about 100 most of the time, with extended periods of less than 100. And not, because we have less players in AH... but because HTC concluded that 600 on a single map is not good for gameplay & business. US players can still play with 200-300 most of the time...
And yes, it's huge difference having 200 players actually fighting, or having 150 in one arena, with many of them just sitting in tower to secure their spot and 50 in the other.
J/k...caps at 400 would be awesome.
Unfortunately, this would make the problem worse. Or do you think 400/400 and 20/400 is going to be more popular?
I'm afraid all solutions consisting of just increasing cap minimum ain't solutions at all.
