Campaign Teleport is pricey?
7 Op credits of Crystal Fist or Crimson Domino will get you a pair of sprint shoes and a bunch of teleports. When is it not available, anyway?
Anyway, seems like you're after concrete reasons, eg items and leveling spots.
There's good, even great, equipment to be found in WotG for other jobs. You shouldn't be surprised there's none for SMN, there usually isn't. Dunno what to tell ya about leveling spots really. Most spots will have the threat of aggro, and with most jobs a tough will kill you just as dead as an IT. The goblin you saw was probably the pioneer; he wanders the whole zone so even if he's in the camp for a while he'll leave soon enough.
