Overall I would say I pretty good informative post for new people to KaW. However, you say you ask yourself why people sell their allies. Well, for me for example, I bought a $2 bil ally and my plunder went down but $300,000 as well as my ally bonus. So from the purchase of the ally I lost $600,000 on my attack. It may not seem like much but my goal is for plunder and ally bonus to go up not down. It's strange to me on why that happened. It was the exact same target both times fully regenerated. Long story short I sold that ally to upgrade and then my plunder went up but I was already at max ally bonus.
