Level cap increase with HW?

[WHS]

It's worth noting that level 52+ skills are learned in Ishgard. While you can happily progress to 60, you won't see much benefit until you can run uncapped content and claim new skills in Ishgard.

I'm confused on what you mean learned in Ishgard as my 52 and 54 BLM skills were learned right in Uldah from my Job NPC.
