meh.. that's just more internet traffic to continually spam the already clogged connections. An additional 8 byte check packet going up and down the pipe every second (or less) may not sound like a whole lot to you, but when you are dealing with about a 200ms (or more) RTT for that check, then multiply that by the hundreds of thousands of players....hello additional lag.

Their networks already suffer enough with stability issues....don't need to poor more salt on an open wound.
