I don't think I'll run the Alibaba adventure to get that tribute. I mean, it's a big loss of troops to get one manuscript per week... It's better to optimize the manuscript production with the RPH.
The crisis quest might be less demanding but still I don't think the effort worth it.
If it is feared that people would abuse of that tribute then: set a suitable production rate and make it not buffable.
Honestly by making quests and events too difficult, the game is losing people interest. For instance: I've discussed with other players about the weekly challenge: most of them have give up with it, most of the time it is simply too hard to complete it. Especially for a few more tokens...
