This thread and the battles I've been mercing for are the veritable proof that NA strat is much weaker than EU's one. When I saw Kalmar's stuff, and what I've been fighting against, I wonder how many time would druzhina spend at taking the totality of the map if they wanted to. They got the totality of NA silver themselves, and almost as much troops, tickets and so on. I'd say around 2 months to take everything, 3 or 4 months if there is actually an alliance of every american clan.
Disclaimer : never said anything about any conquest of the map, just an observation.
On topic, I'd say Kalmars should be taken seriously, since even with 120/130 ping, some players manage to do incredible ratios in strat battles.
