Refunded for Heavensward.

"sufficient progress in the main scenario" isn't very descriptive. Considering I had saved the world by lv50, one would think I have made sufficient progress.

In an MMO where the story isn't as connected and each expansion starts as essentially a new story, probably. I'd think that by level 50 though you'd have picked up on how important story progression is in this game, so 2.1 to 2.5 being used to tell the story that connects 2.0 to 3.0 should not have come as a surprise.

Technically, the start of the story for Ishgard begins around level 35 or so when you first visit Coerthas...it's much more like the next chapter in a book rather than the next story in a collection of short stories (which is the more common approach in MMO expansions).
