Very hard difficulty: individual opinions. Ever played rogue-like game where you die easily and you have to start all over again? (no save points) I just think about those impossible missions like those games. Just learn the pattern n timing and eventually you can beat it. It's not designed to be beaten first time (grats if you can beat it first time tho!) and since I'm also one of those who get stressed easily, I only play skirmish for actual play and watch playthrough for the missions.
About no new releases: You have no right to make them look bad just because they haven't post new public releases. It's a completely free to play game (not even in-game purchases). Long waiting time is always acceptable for fully free games. If they managed to release new ones fast, respect them. If they took a really long time to release new ones, help them the best way you can to fasten the process.
I myself can't wait to try the new units, the new voxel arts, the new strategies, etc. But I would rather keep waiting rather than having the game with bugs. There are other games I can play whilst waiting for BR2 anyway.
