This is very INCORRECT statement. You guys here are missing one very significant point which I mentioned before. Not the time how fast you can get to 8.4aa and get new town, but time how fast A WORKING PERSON can get 1900 + 710 (610) pots of gold. Repeatedly. So it is 11 days to go = 11 days in the event, just half, right? I am at quest 36. I couldn't, literally physically couldn't do more quests until today because of my real life workload during the week. And that's fact which is ignored by all the strategists here. So far I finished one town with fully opened chests and now I have 1.2k gold = not enough to open full set of chests, can't even do that yet because I have aprox. 1aa of shamrocks and on top of it I didn't do enough tasks to get enough grand prizes because I'm stuck with 3 tasks being managers... which in turn I don't have gold for.
So I can only repeat what I stated before - for person, who like me works in the environment where he/she cannot play the game at work (I am trucker, so I really can't), this event is impossible to complete, period. No matter the strategy. because you will not get required amount of pot of golds at the day you need it, if you cannot rush through the first 35 quests in couple afternoons to stockpile them. And you can't with like 20x 4 hours production (sorry, I don't have even 20 backsmiths in my city) and such.
The ONLY solution is to make grand prize every OTHER prize, not every third and to make tasks skippable or program it so that there is never all three tasks manager.
If this two things are not implemented, it is not even worth to start the event for working person, because he/she will became very very frustrated and angry. No strategy can fix this.
