After you build a little bit and finish most start-up quests, instead of Homeland goblins e.t.c the focus should switch to defending your homeland against PvP attack. And given a growing player population, that`s turning into reality.
However, we do plan to add some more homeland attack events from creeps - mainly large stuff like Dragons though.
And in the exploration mode, if you are playing as Humans, and you explore human regions - Orange and Yellow stuff is Friendly, until you purposely kill any of them of their units, at that point they`ll start hunting you down. So feel free to hunt Goblins e.t.c
