The spawn time currently in BTB Skirmish is only 3 Secs but players do not get punished enough for dying making pushing extremely difficult even when you are slaying the other team. Therefore I feel that it is necessary that spawn time be increased to 10 seconds to promote team pushes once you get a few players on the opposing team down.
Also I would like to see CTF on Settler.
Ammo should be scattered throughout the maps.
Lastly, the enemy team should NOT be able to spawn at your base.
