Instances are not a valid source of EXP.

[Kazamoto]

Gear all the way up to level 50 is transitional gear. There is no point in repeating instances to get the items you want, nor is there a real point to adding materia to gear before level 50. This is yet another reason players will not be repeating instances.

This is why we get tanks in Main story dungeons in all white gear with no rings/earrings etc.

You should always have good gear for the level of your next or current dungeon, if not you are a drag to the rest of the group running the event. At least in FFXI when people pulled this "only end game gear" or "its just a sub job, i dont need good gear" crap we could kick them.

While maybe YOU dont care about the content until 50, you party likely does, don't be a jerk kupo!
