It is the time to bring your toons that are not max level yet. We'll do the heroics and dailies in the different daily area like the Black Hole, Oricon, Yavin 4, Section X, and CZ-198.
Levelling your reputation with those groups gives you access to armour, dyes, mounts, and more.
It is also a good thing to do to get conquest.
Some daily missions from the Galactic Season also requires you do to a daily area. we might get lucky and get a daily linked to the dailies
There is no requirement other than having your ship. We'll decide which ones we'll do with the group at the start of the event.
You can put your request here or at the start of the event.
