You can put something on the shelf and not consider it a failure. We do the same thing with all kinds of content. Rush to get what we want from it, then move on to something else. Most of us will be back when they provide updates to Blu, won't we? Try out the next new spells, new carnival fights, increased level cap and see the job quests. For what it's worth I will continue using Blu at least a little every week for the weekly rewards. Poetics can buy materia VI now, and allied seals for aetheryte tickets or ventures.
