I don’t want to call this cheating, since the game allows it. So flare should take some measures to prevent it, if they don’t it’s fair, since it is allowed.
I would definitely call it unfair play against the other alliance, albeit I respect opinions of others. Just keep 8-10 best members in with tough bases (8 members is minimum limit of alliances) and let all others return in last hour of the fight to score heavily. Big chance you win the fight if scenario works well, unless your strongest players aren’t as strong as you thought they would be and are beaten by almost every player of the other alliance. I would consider it funny when players kicked out temporary are no longer willing to join the alliance at all and this miscalculation causes losing the war. It could be clever tactics, but doesn’t deserve a price.
Could definitely work for an alliance where all members come from almost same region, but not for alliances with members spreaded all over the world.
But to be honest, how would you feel if you are one of the players who is kicked out temporary just to win or better said, prevent losing a war? Even if I knew it was temporary and it also clearly announced by the team, I still would feel bad, since I was considered not good enough to fight during war season. And since I don’t like cheap tricks to win a war, I would definitely reconsider to be a member of such an alliance. I would rather lose in a fair way with complete team without any excuses, then to win by using tactics like this.
Fortunately our alliance fights fair and that makes me proud to be a member of it.
The rule should be changed completely and just eliminate the 60 hour codown period. Change the rule, players can only join/leave alliance during cooldown period between war seasons. then these tricks are banned out, no excuses no cheap tricks. just fight for what you are worth for as an alliance, one against one.
