From what I have seen so far in Phi it certainly seems that way. I've seen many alliances that have at least 10 pacts and I'm wondering "why would any alliance want to get that many pacts." Sure, pacts help with reducing the number of people that can attack you but they also reduce the number of people that you and your fellow alliance members can attack. Like Fist of the North Start said on an earlier post: Grepolis is a war game, you're supposed to attack, spy, and conquer players of opposing alliances. It's what makes this game so much fun. Heaps of pacts, in my opinion, just take away from the value of the game and eventually you're left with a cheap knock-off of SimCity where all you do is build, build, build.
