I was in BAD and what's the point in disbanding a tribe with lvl 43 skill? There was a inside man in P&D and he some how managed to get the founder rights after BAD made P&D leadership mysteriously quit, then our leaders went over took the rights and proceeded to kick like 75% of the tribe. If NAN said they would have turned the offer down they are liars they wouldn't have, neither would most people. So I actually see it as jealousy that everyone criticises it, it was a very good move that most people would find hard to pull off.
The only proper merge was between veteran kings into BAD, besides that BAD didn't merge with anyone.
Either way this world was merges all the way through.
N&W + TSC + S-C = NOOBS + T-P + Ao1 + Yak = WIN
Wars .... TCW vs YAK and NOOBS.
So you have 6 tribes merging together (NOOBS) against 2 tribes merging together (BAD).
