Okay thanks. I was just worried that weapon rankings were set in stone and unchangeable. I have no issue with starting at E as grinding is natural to me as a gamer. It's how I always play RPGs.

With grinding weapon ranks I try to go through a logical flow that lets me build up a new weapon type while still keeping a maxxed-out weapon on hand.

Cordelia, for example, has access to all six weapon types between Falcon Knight, Dark Flier, Hero, Bow Knight, Sorceror, and Dark Knight.

Assuming I promote her to Falcon Knight first, she'll have max Lance and Staff proficiency. A chain of Falcon Knight -> Dark Flier -> Sorceror -> Dark Knight -> Hero -> Bow Knight ensures she always has an A-rank weapon on hand while she builds up Tomes, Swords, Axes, and Bows in that order. Hero and Bow Knight are interchangeable since they both use Swords, and none of her other classes use Axes or Bows save for Bride (And Cordelia will never be a bride because Chrom doesn't love her).
