... will be a lot less dramatic then what you were hoping for.
You see here's the thing, for any alliance you need to constantly gain new members, to replace the ones, that lose interest and delete, especially if you are going to grow. Most alliances do this by recruiting new players in CN. For Gramlins though, they have to accept new members by having experienced players wanting to come to them, or by seeking out experienced players. The result of this is that the Gramlins must rely on their reputation to attract new members.
Now that they have trashed that reputation, they won't be attracting new members, which means no growth. They will slowly lose members to deletions, and then more will realize that the alliance is a sinking ship and will leave. If they ever do repair their reputation from the latest fiascoes (don't forget Muto going rogue against them), they will have the new stigma of being a sinking ship to deal with. We may be hoping for them to be destroyed in war, but they will fold the slow way that is the end of most alliances. So in conclusion The Gramlin's bad reputation will stop them from being able to add new members to their fold and cause them slowly dwindle away.
So what do you think, am I right, or is this one of my many wrong opinions?
Prediction: Jack Diorno will reply to this saying that him joining Gramlins disproves my point that they will no longer attract new members.
