not only will it put you into the system im in (Naboo > Moenia) but itll save me an assload of typing. IT DOESNT MATTER what you start as for the most part. this is a sandbox, you can change and do w/e you want. just start off scout and do tutorial for the ease of everything. the biggest decision you need to make soon after starting is do you want to be melee or range. in the tutorial i think it trains you in brawling (melee) but right afterwards you can do marksman. you can train both to see which one you like but need to pick one or the other so you can pvp/grind.
