Sweden is indeed a tad too passive, but IMO her choice of allies is even more worrying. She allies with Russia and Denmark more often than not. (The logical choice would be Poland). Anyway, with IGC2.0k, Sweden seems more likely to expand in the Baltic. I recommend choosing the "Teutonic Order Ingermanland" option in the IGCConfig as it seems to put Sweden on the right track.
For the record, Ingermanland, Estonia, Livonia and Kurland are all considered Swedish core provinces in the IGC.
