I played on almost every map and i can tell u that there is no big difference.
Extinction is the worst. I cant fly to the city on our server because i get disconnected every time. I got about 10 disconnects after every 2 minutes and a tribemate had to get my wyvern so i can spawn somewhere else. I also get a few second long freezes everywhere on the map.
On Aberration and scorched earth ragnarok or valguero i get sometimes disconnects, no difference
