Theories with the where the removed stuff will go.
Nanamo Minion:
- The Revelations that comes with the removal means that she will not be a quest reward outside of a retconned-in achievement (and if she is a quest reward, that means 2.4 won;t be the end of the Teledgi subplot). However I don't think that means she'll be a Ultra Rare dungeon drop (unless dungeon minions are always added in mid patches). Possibilities are Achievement reward, story quest in 2.5, cash-shop or Hunt seal item. Maybe she might be connected to the removed Moogle Mail quest that were apparently removed
Urianger Minion
- Urianger is connected to the Binding Coil storyline so the minion might be a reward for clearing Final Coil or maybe beating the Savage versions of all three (the latter getting around the fridge logic of "if he's meant to be a Coil reward, why remove him from the same patch as Final Coil?" as HM versions of Coil are usually concurrent with nerfs to the raid. (as well as give another incentive to actually try the savage versions
Metallic Dyes
- The Gold and Silver dyes were not implimented at 2.30 either, So it would seem likely that the dyes will be implemented at the end of the patch cycle. Retainer Ventures are the likely possibility besides Cashshop.
