The WoE FE GDs are pretty awesome with gsbs and stuff, makes it worth the time going down there.
But for SE GD, this is not the case, other than the abysmally low drop rated Elementary swords, theres is nothing worthy to be found down there, not to mention the mobs are thinner and hit much hard.
Also SE takes up more supplies, maybe add GSBs at a bit higher rate or something ? Maybe it wont remain dead content like 80% of the maps then.
