The war weights are off for Digital Age accounts.
Many upgrades for Digital Age done to defending structures do not represent a correct war weight.
For example: Maxed Bunker in SA has lets say 300 war weight points (280-250-200-180, etc for lower levels). The DA bunker has no points (BHG forgot to assign points for the new level of bunker). Now every DA player who has just upgraded a Bunker is losing 300 war weight points/ upgraded bunker. He falls down in war ranks and it is also decreasing the war weight of the alliance. The same might be true for troop upgrades... If a DA Heavy Tank (mk10) is researched, the account is losing the HT mk9's war weight points, but not getting new war weight points for the new HT, as BHG forgot to do their homework...
That is how mismatches are born these days.
The task is to get the war weights right for every Digital Age upgrade (towers, traps, depots, bunkers, silo, etc...), and then the new system will do its task, till then all efforts with tweaking the war searches are futile...
