The weeklys are rather aimed at level 30, that is less cool, if my suggestion in other thread to adapt missions to class-progress is picked up that would not matter though.
As for Mission Variety (I guess that’s what the thread is about?):
I liked that it’s not all linear, but that now and then there’s “any” missions or go back to HS, Rainforest. And the last, ruined potion one was hilarious
Kill Missions: I liked the kill number x, number y best, and amongst those the ones where mob-types are explicitly listed; I would like to have these for all mob-types (I think in rainforest there were barely any). There’s few (Witch, Tree Guy) which are meant for a group, that could perhaps be indicated so new players don’t need to die to find out.
Fishing: It is good that there’s not so many fish required, because it takes the most time and is easy to overlevel. Other than that fishing either weight/type is fine.
BG Missions: Should be entirely optional for progress. There are 22 missions I can not do, I am queuing for hours, never get ported in. I wished there were more types like a smaller bg or duel-missions instead, so those who play at times with low player-count can do some.
Dungeon Missions: Should be de-attached from levels since it’s hard to find groups at this exact level, most will overlevel these.
Salvaging: I second Atropos’ suggestion, find x of these type could happen more
Critter Hunt, Events, Dragon Quests: These seemed all fine, only some races I found to hard…
I seriously don’t have many new ideas since those are not the “classic” quests and for missions the x of this, y of this is the most logical.
New Mission Types: Would be perhaps nice to explore more, like find things/view points/portal stones in the world. Or talk to npcs, but that rather fits to the lore quests.
