The reason the ping limit is 1000 is probably because War-Lords is active more than you might be on Rival and those people may be from a different time zone and have shitty pings, but they play against people with shitty pings as well. Its real interesting for me to go into a server that isnt very populated at a weird time and one deag every over 500 pinger lol idk how I do it, but it just happens a lot. Asian people have the worst time with this surprisingly because internet is shit over there combined with connecting over the ocean, it can be like over 700 ping at times
