5.22 Guinsoo's Rageblade

There may be several questions about every single thing.

I'm asking about Guinsoo's Rageblade.

Could you divide the first two items into cheaper? (for early/mid game) Are there reasons for not doing this?

Is there some plans for Rageblade after 5.22? Are there plans for all 5.22 items after release?
