Actually hansel is the best build when it comes to... Everything. Terms of war? Can self pin, assassinate uses little spies, and burns pots. Or can make cash stealing. For plunder wars? Has good attack, with usually best average "troop bonus doesn't plummet every hit", and with high spies can gain a ton per steal. On top of that much lower stat total then a say, pure defense build "titans lair" ETC;
It all depends on your playing style in my opinion, if you can only unload your attack troops due to other commitments then a heavy attack with a few SOS's will benefit you. However if you are active often a Hansel or a hybrid build would be a good option. However do not just discard the heavier attack build, if you slow hit (2 attacks allow to regen) you can gain really high plunder. This is just my personal opinion, if you need any advice or help message me in-game. Thanks
