I don't make it a habit to come on here and badmouth the "enemy". But I think it's safe to say that Mercs is bloated, disorganized and completely impotent at taking anything of substance. Soulcatchers and Infection have about a 75% or higher success rate in taking their cities. Mercs have MAYBE a 20% success rate at taking cities belonging to WTE. And they've never come close to taking a city from Soulcatchers or Infection.
Mercs are simply outclassed, simply put.
The main problem with Merc from first hand experience by myself is the MRA diplomacy they maintain. They have alliances and pacts with so many people it's hard to keep up with. They make deals and then break them. Form alliances from members of their overall group and operate some kind covert action or disguise a future course of action. All of which is so easy to spot by anyone with any kind of grepo experience.
For instance I had a very simple deal ... Merc and their allies do not cross into 65 and Mamluks don't cross into 55. Then what happens, their allies and even themselves started crossing the border, and the group finally went from 26 to 58 cities in 65 with the principle offender being Lords of Olympus and their sister alliance. The only time we went into 55 was to go after Final Destiny who attacked us and were pushing for a fight against us. We offered to swap the cities we took from FD in 55 and LOO passed or couldn't make it happen.
Then LOO broke the NAP and we invaded after one too many breaks of our agreement and from what they tell me Merc cut them off and we rolled over LOO and we are now in 55 to stay which I guess we can acknowledge that our deal is broken. The constant breaking of our agreement had me spending more time looking for infractions than playing the game. So if you make a deal with Merc it tends to last as long as they need it to
The latest issue is Merc took in players with 65 cities and when we wrote to them about their status to us ... they ignored that message.
Now what happens this morning, an alliance founder of one of these alliances in the Merc circle, talks down to my diplomat and claims he will only speak to worthy players from my alliance. Well that won't stand and I told him so. It seems if you make a deal with Merc and now all of a sudden an alliance a third of the Mamluk size thinks they can beat us.
Personally my view is that if you make a deal you stick with it as best you can and not try to get around in some sneaky way the intent of the agreement. MRA's do not share that view and it almost always cost them dearly.
