Im playing with the Geisa mod pack and the Polish are struggling but they manage to valiantly hold on, Warsaw alone has swapped hands betwen the Russians, Swedish, Cossacks and Polish. In fact their doing a lot better than the Cossacks who only hold about two cities and a handful of fortresses, the rest have been taken over by the Crimeans (which im fighting my own war with since im not aligned with any faction). Also, ive seen their armies in about groups of four or five but that probably because they only have about 40-50 troops each. As far as I checked they have about 13 armies compared to everyone else's 19.
