Ok so, my router's QoS system does not want to recognise Gunz packets as important enough to bump them up the priority list.
With my previous router, my benchmark test was to do a pingtest.net test to Sioux location in the US, which was around 130 ms, same as now. But now pings in Gunz are double the usual o.O
