The hoarding system is great in that it allows you to plow through tons of leves at once basically turning them into repeatable quests from other MMORPGs. The thing about repeatable quests that it lacks is the convienience of the quest NPC being on location.
Instead of accepting what amounts to delivery quests from Ul'dah to turn a pile of materials into something Camp Horizon needs, the pile of junk should be at the camp already. Interacting with the crystal or NPC at Camp Horizon would then allow you to repeat the leve indefinately saving the step of traveling back and forth to Ul'dah every time. The same can be done with battlecraft and fieldcraft leves.
If I want to spend my 50 leve quests grinding pugilist in Nawana Mines I should be able to do so without the time-consuming step of travelling back and forth every 3 quests.
With the new system allowing focused leve usage and becoming what amounts to the equivilant of repeatable quests in every other MMORPG, the next step remains to add the convienience of this repeatable mechanic by removing travel and allowing on-location acceptance of leves.
