I wonder when they gonna add in Abyssinia and the meteor crash side mission.
Youp I too felt like the last currently available tile was easier than Ocica.

One the note of Ocica - I have been farming it for the last...4 days ? 5 ? maybe a week.
So far I got lucky twice - 1st was a 5* Armor Penetration Embelm (very solid piece, Victoria was very satisfied with it), and 1 4* Dupe KV-2 Veronica. So yes the odds are small, but not non existent if you run that map over and over and over again.
Plus since I am L50 the scaling has stopped and after my "Tank" tanks have leveled once or twice they die a lot less than how they used to before. No idea how hard the next event is going to be, but its nice to know that the "running up the hill" part of the game is over for me, and now its all about playing catch up for my units, until the whole team hits L50 as well.
