Rarity no longer tells the whole charge story
The official 0.4.0.84 notes standardize all armor plates to 10 replication charges regardless of rarity. That is a live-balance statement, not a permanent rule for every future patch.
Practical use
Check the in-game item panel before spending materials. Plan replacement gear around the actual current charge count and cost, rather than a remembered value from a previous version.
