I think that Vinster is on to something. MRT was crawling towards victory and if everyone in that tribe has kept their current pace, victory would have been won in 3-4 months. 3-4 long, slow, grueling suicide and coma inducing months.
Since MRT leadership failed to merge with their obvious partner OS and failed to motivate rapid.active growth, it makes sense to start a new tribe that will attract all the active players. They can grow quickly thru recruitment and active acquisition of new villages.
