Missable items temporary list

[Shougun]

You're saying the Fisher secondary is confirmed missable, it's not. From the post you linked:

Greetings!

Apologies that information on spearfishing achievements was not included previously, as many of you are curious as to what will happen. Since spearfishing is being removed from the game when A Realm Reborn rolls around, it will also no longer be possible to complete spearfishing achievements. We will add this to the list when we release the topics announcement we are currently working on, outlining various aspects of change.

Perhaps Fishers Secondary tool will transform into another tool type entirely, but the spearfish item is being removed from the game.
