With the addition of sailing... we're really overdue for a achievement diary rework

At this point, just pull the trigger on updating the achievement diaries to actually match current game content. Hell, even add a Master tier.

Current state of diaries is completely outdated rewards, huge/important pieces of content missing from certain areas (vork with fremmy, toa/temp/giants foundry for desert, gotr/tds for lumby, etc etc etc), omits entire quests, and now doesn't even include an entire skill.

IMO just overhaul it and dont be afraid to add or change requirements for easy/medium/hard diaries. rip the bandaid off.
