From the event listing it says
1. In order to receive all 5 items you need 290 golden clover. From daily quests alone you can receive 256 golden clovers and from the 48 hour tasks you can have 182 as well as an additional 200 golden clovers from the weekly tasks
So IF a person could possibly do every single thing there is a possible 638 clovers but , since so many of them are next to impossible there isn't a way for most people to do even half of those tasks.
and it says
2. The Daily and 48 hour quests are very easy to do, and many of them can be completed within a short period of time
ha, not true, I don't see the ones that are 'easy' I see plenty that are impossible or nearly so, such as the one that needs 3 one hit wins,. You took out the quest from last years event that needed one to replace it with 3 KO, but for this event you think someone can do 3 one hits, [somebody takes some strange drugs at InnoGames]
it also says:
all quests are divided between various areas of the game to ensure all players have the chance to complete quests relating to, at least, one area of the game that they enjoy.
Proportion wise this is not true, the majority of what I see is duel related, followed by fort and adventure, still looking for something I enjoy, I sure don't enjoy people KOing me. where is the love for the "berry pickers"?
finally the truth is mentioned, that it is all a nugget grab
6. The Golden Clovers will be available in the SHOP at a later date, should players wish to purchase extra pieces.
I don't and I won't
