No, they are not working with gents, they dislike IT because of the way they do diplomacy. They came to them looking for some sort of NAP/Alliance, then ask other tribes to gank up on them. So now they are taking them down
I'm pretty sure its not entirely IT's fault.
Forgot even came to my tribe's Ialone before for a merge then the merge fell apart on the first day or second day because a baron literally wanted 100% access(sitting) to all our accounts for atleast 1 hour. And that's that, my duke was pissed, it was bad to the point where reconciliation was not an option.
And whilst i was in there, they were getting nobled by reason, they werent the only tribe to be pressured by big tribes. Either Gents or IT couldv come to the rim and ate us all up.
IT just did it ahead since Gents was busy merging/recruiting their war enemies. Probably, im basing this on my LIMITED knowledge.
And when your eating big tribes like echo and dismantling a tribe like MVDC, its inevitable to have reactions from the other tribes.
P.S. im probably gonna be flamed by what i just said, sigh... well, its just my opinion anyways, its all based on my limited knowledge and an outsider's perspective.
