I run an average size guild of 12. Half consider vikings at best, a waste of effort. At least 3 of those 5 have worked out, destruction and reconstruction is the key. This has not spurred enthusiasm, but rather, has killed the whole concept for the 5. The remaining members of the guild have not responded so, they are either not doing the minigame or are spending diamonds to do so. The only reason i am still doing it is to confirm, that the game cannot be won without massive expenditure of diamonds. I am a bit bloody minded that way. But after completing 11 quests, i doubt i will be going any further. The concept does nothing to endear itself to my guild. I won't obviously, can't speak for others.
