As the leader of an Alliance, I love it. I can view my Team's attacks and see where we have problems. I can give them advice and point them to examples that illustrate my recommendations.
Some people are complaining about the strategic advantage that it provides the enemy. They didn't like the fact that others could see the locations of traps and hard defenses. I think this adds a whole new dimension to the strategic nature of the War. It's like gathering intelligence. If the Leader is doing their job and providing direction to their team, it can provide a big advantage. If they are lazy and not good leaders, the members can still scout more effectively. This provides an advantage to having previously attacked and lost, or only received minimal stars. For example, one of our recent enimies had a bazooka tower well hidden, and well placed. After two catastrophic losses by higher level players, we were able to point out the tower and take them out on the third try. It promotes more teamwork and makes the game more fun.
Oh, I like that you can see if your donated troops and/or tactics do any good. I had donated some level 6 fire throwers to an enlightenment age ally and got to watch them devistate the attackers. This makes me want to donate more tactics, which will translate to increased profits.
Speaking of profits. I was so fed up with where the game has been heading that I was ready to give it up. Even though I still don't appreciate the greed, this feature has restored my interest, for now. At least I feel like I am getting something for all of the money I have spent.
