www.nacrpg.net is now recording Kill Streaks. If you live between rounds, your streak is still live unless you are switched teams. If the map changes, your streak might still continue as well if your on the same team as the last map.
You can view stats by going to player stats, selecting region, then game mode or leave it for total.
Servers recording stats:
NA-100
NA-80
NA-Siege
NA-Duel
EU-Shogunate
More to come hopefully:
EU_Pecores
NA_Blackrose
EU_Kapikulu
Next Project for stats:
A nemesis feature that records who you have killed the most and who has killed you the most.
