maybe it could be possible to merge some regions in northern europe(thus getting rid of 1-2 provinces) and one in each arabia and Britain but more would not be worth it imoas it would take away to much focus from regions that were added only by eb in the first place. an other option would be to declare large quantities of the european steppes "eremos" this would sound a bit silly tho

still I'm fine with the EB 1 map and anticipate the EB 2 map to be even a little bit better
