yesterday, I did the random town attack. I would only send 1 nerd per building, and would only do as many buildings as were on the landing screen.
I woke up to almost 3,986 elixir this morning (sorry I don't know how much gold).
That's pretty good, and means that a lot of my attacks were successful. Now part of the reason for that was because my neighbor lists for visits is all messed up from figuring out a strategy for myself, so I'm letting them all reset, and then I will start helping my neighbors out.
It's clear to me that the best personal approach is random attacks, however there is plenty of time for the event so I'm going to do what I can to help friends. If I'm wanting more castle walls / hay bales / etc when the time starts to wind down, I will switch to randoms again so I can boost my elixir.
I wish the neighbor screen showed how many attacks I have left for a town, that's frustrating.
@WS_7 - the problem with your strategy is the length of time for attacks to be successful. A level 1 house takes 9 hours with 1 nerd. if you have even a half full neighbor list, that's 250 attacks, per day that you need to allow to complete and clear. Even if all you do is play this game, you would probably need close to 75 attack-able buildings, and for your friends to attack in a staggered enough pattern that those 75 aren't all being attacked at the same time.
The true best of both worlds (to me). Is to have a handful of neighbors that you can alternate revenge on.
neighbor attacks castle
you defend and revenge
rinse and repeat until your daily maximum is hit. You get defend rewards, neighbor gets max non-destroy rewards. and your castles are still available for others.
