So I will try myself on a mapguide to Settler now, for Hogging and maybe general playstyle of the map.I mostly played this map with little groups so I can't say how 2 Partys of 8 will turn out on this map.
If I recall correctly this map can be found in the CTF,BTIS and BTB skirmish (regicide) playlist.
Settler is an OK hogging map,it has a lot of hills and bumps everywhere, which you can alos use to hide or gain advantage.
Important things first: Controling the Hill (on the right in pic 1) is kinda like Topmid for Ragnarok ,your team has to hold this Hill otherwise the other team sits up there and Hogging isn't much fun then. Why? the have the height advantage ,they have lots of covers, a Railgun spwans there like every minute or 2 and it deals great amount of damage to the warthog and can flip him (pic 2).The Railgun is also a 1 shot kills on footsoldiers .Driving up there while the enemys holding it results most of the times in a sure death and destroyed warthog.
In the beginning of the game I always hide behind either a rock (red base/pic 3) or a wall on the right (blue base).Alot of players just rush forward which brings them in our half and we got teamshot assistance for taking the enemy hog out.If they don't rush i look if I can support the "Hilltakers" . Often when one team gets pushed back people drop down the hill through the gaps in the wall and offer themselves as a easy cleanup.
