Hi guys. having this idea for awhile, thought id post it here. you can have nations branch off major nations like so

UKdd1->UKdd2-> Canadian DD1-Canadian-DD2->CA CL1
UKDD1->UKdd2->AussieDD1->Aussie DD2-> Aussie CL1->Aussie CL2->Aussie CA
UKDD1->UKDD2-> Greek DD1-> Greek DD2-> Greek CA-> Greek BB1 (endline)
GermanyDD1->KMDD2->FinnishDD1->Finnish DD2-> Finnish CA
IJNDD1->IJNDD2-> Siam DD1-> Siam CL1
look, i know this is farfetched but its just and idea. dont flame me please.
