Loyalty is a thing of the past.
There was a time when alliances would stay together for years at a time. When anyone leaving an alliance was because of an emergency or personal. All that changed with the introduction of AW season 2. Now turnover is horrible. Top tier alliances require perfect play or you're kicked and lower tier players are always jumping to the "next best alliance". The whole mentality now is that the grass is always greener on the other side. No one wants to put time into building a solid group. There's no patience with newer players. It's all about chasing those AW rewards. In my opinion, alliances were founded with the intention of having a group to grow with and battle with, through think and thin. Build friendships and not only enjoy the game but the people you're playing with. AW has all but killed that now and it's a shame.
