Yup, it's all about layout.
For example Tatooine, which i thought would be a nice gankfest leveling planet is actually just split in 2. North part of Tat is Republic, and South is Empire. All your factions quests exist within your side of the planet.
So if you want to look for pvp and grief questers you go into their side. Instead of like most MMO's where you are fighting over the same quest areas. SWTOR makes you go out of your way to grief questers as it's "world pvp".
Maybe this gets better on other planets but I hope paths cross more often later.
