There isn't that big of a difference between the alliances in my opinion since Sandhurst literally did nothing in the alliance as founder and homey did all the work. Now Homey is the founder of the dulce.
Which is a mistake, the old alliance suffered for it. Hopefully the new one doesn't. There is almost a 50% difference in membership, that's a civil war/split or alliance breakup. If basically everyone but the banned founder made the switch over to the new alliance, I think there would have been a better argument. (Which still fails imho)
Also, I have seen alliances still stand and survive after the only one with founder rights was banned. They went through support and resolved the rights issue I believe, I don't remember all of the details but there are always options.
I don't know, I guess my biggest problem is that its just simply not the same alliance, half of the member base was left in the dust during the split. They weren't kicked or booted through alliance maintenance measures. They were just left... There is a reason ABP and DBP point totals from members don't move from alliance to alliance and its simply a bizarre way to say you should be able to and no one else can.
Game mechanics are what they are. I work hard to make sure The Hive is situated for long term success. We as a team work hard to make sure every possible measure we can predict as a possibility is accounted for. Your old alliance simply failed to do this or it wouldn't even be a question. Alliances should have leadership that prepares for everything.
It's a hard argument to say "we lost control our alliance, but we want credit for what the lost alliance did"...
