Yes and there are few reasons to it. When planning where to place a guildhall a lot of considerations were made and all the planets were scouted.
- It’s placed very close to the busiest starport on Corellia
- Probably more than 50-100 vendors are just near the guildhall. (open in-game map, chose vendors on the right side and see for yourself)
- Corellia is the most centered planet, with only 1 starport jump to most of the planets.
- 24/7 Entertainer and Doctor buffs at medical center and cantina.
