Alright you know I have great respect for MOS and all of its players so all of this is said with no disrespect, but I will give my version/opinion of why the world is the way it is.
1. Pacts - when MOS reformed into a super group like they were they should not of had any pacts. Think if you guys would of had no pacts with anyone at the beginning, you would of been fighting everyone on all fronts. Yes this would of been more challenging, but it would of been much more fun for you guys as well and given other alliances more of a chance. PB took this approach on Corinth and it made the server more intresting imo. It made all the other alliances sort of unite in everyone vs PB mentality. So although they were an amazing team it still gave the other alliances a sliver of hope and a reason to fight. As it stands now the second and third ranked alliance on the server are both allies with MOS. This is obviously no accident. The way you guys fought at first you were fighting one or two legit alliances at a time with an ally (BoM). Fighting this way made it much easier for you guys to assert early dominance. Once you gained the advantage early by doing this it became nearly impossible for anyone to really match you. Another example of pacts, your war against Silver, think if you would of fought Silver and TSL at the same time instead of pacting with TSL. This would of made the fight much much tougher for you guys, at the same time much more interesting.
As far as a solution goes, I have a few ideas.
1. I know this option isn't appealing, but drop your pacts. I am sure some will give me some flak for this, but think if you were to take on TSL and BoM along with your current wars. This would give you guys plenty of fighting to do and make the server more interesting as a whole. It would actually make it seem like their is a chance you could be defeated, if you would actually lose or not obviously cant be known. It would at least give a glimmer of hope to others though.
2. Someone suggested the disbanding and doing all that option. I agree that could spice up the server a bit if you guys chose to do that.
3. Split into two separate groups. Split your alliance into two seperate alliances and fight each other. Obviously no one wants to fight their alliance mates, but some of my better friends on grepo have been in enemey alliances. You could divide the alliance up multiple ways. One, just alternate every other player and split it that way, I think this would be more fun as it would create utter chaos with many players having cities on the same island as each other. Two, try to split it up geographically. Meaning that you would try to split the players as to have a dividing line. This would obviously be much more difficult to do as your cities are obviously all mingled together.
In conclusion I understand you guys want the server to be more interesting, but short of any of these things happening I don't see it becoming more interesting. You guys are clearly the biggest most dominant alliance at the moment. Sure there is a few alliances left for you to fight such as EO, but how long would that war really last? I cant imagine to incredibly long. Anyway everyone feel free to be as angry as you want with my post, but short of these things happening as long as MOS doesn't have an incredible amount of their players leave they will sit atop the rankings uncontested until WW time starts, they will inevitably win those as well.
