Northrend villages weren't mentioned much since they were early destroyed.
Gilneas is probably rotting since they aren't part of alliance.
Kul Tiras is probably scared since their king is dead and their allies are falling one by one.
Alterac was destroyed in second war (great mission). They were allies with the horde so alliance attacked them. Latter they were nothing more then bandits who raided nearby kingdoms. They even helped Ner'zhul when he was searching for artifacts to open new portals. They were nothing but cowards.
The truth is that Blizzard has forgotten about them because they didn't have where to put them in WoW. They aren't even on the map.
The conclusion= 4 kingdoms destroyed (lordearon is now Undercity), 1 left alliance, 1 is still n alliance but who cares, and one is being finally rebuilted, and one was forgotten since Warcraft 2 (Tol Barad) and 1 new kingdom
So basically alliance is the shadow of its former glory..
