What is the planetary leveling path in SWTOR?
Consolidating from Powerlord's and Artein's excellent answers.
For Empire, the order appears to be:
- Korriban (Imperial) / Hutta
- Dromund Kaas (Imperial)
- Balmorra
- Nar Shaddaa
- Tatooine
- Alderaan
- Taris (Imperial)
- Quesh
- Hoth
- Belsavis
- Voss
- Corellia
- Ilum
- Makeb
- Rishi
- Yavin 4
For Republic it's
- Tython / Ord Mantell (Lvl 1-10)
- Coruscant (Lvl 10-16)
- Taris (Lvl 16-20)
- Nar Shaddaa (Lvl 20-24)
- Tatooine (Lvl 24-28)
- Alderaan (Lvl 28-32)
- Balmorra (Lvl 32-36)
- Quesh (Lvl 36-37)
- Hoth (Lvl 37-41)
- Belsavis (Lvl 41-44)
- Voss (Lvl 44-47)
- Corellia (Lvl 47-50)
- Ilum (Lvl 50)
- Makeb (Lvl 50-55)
- Rishi (Lvl 55-57)
- Yavin 4 (Lvl 57-60)
For Republic it's
- Tython / Ord Mantell
- Coruscant
- Taris
- Nar Shaddaa
- Tatooine
- Alderaan
- Balmorra
- Quesh
- Hoth
- Belsavis
- Voss
- Corellia
- Ilum
Something like this. But there are times that you're going back to some planets to do a quest or two.
After your starting planet, the planets appear to be in the same order for everyone in your faction.
For Empire, the order appears to be:
- Korriban (Imperial) / Hutta
- Dromund Kaas (Imperial)
- Balmorra
- Nar Shaddaa
- Tatooine
- Alderaan
- Taris (Imperial)
- Quesh
- Hoth
- Belsavis
- Voss
- Corellia
- Ilum
Note: I only know for sure through Alderaan because of where I am in the game. The others are speculation based on the level ranges on the star map.
For the Republic, the notable changes would be starting on Tython / Ord Mantel and moving on to Coruscant. Likely, Taris would also be changed out, but I don't know to what.
