SO what do we get in Great Ocean (exept for Khan WB) to help our characters progress, when we can complete ALL quest even without going to G.O.?


Just remove the Great Ocean if you can't change it. It's a dead content.

Obviously you get nothing, for now.
But why remove it ? It's a nice content for players who get there for the first time. It may not seem important for you but this is story driven rpg, all early game npc's and locations doesnt make you progress either but they re still there for this reason.
