I remember your message about this, but I haven't had the chance to sit down and check it out. I'll need to test it.
There are a few more nuances, I'll need to check them out and then I'll write in more detail.
On the topic of "what to play," there's this small but interesting puzzle map. I haven't played it completely, but I liked the beginning; the battles with small armies are interesting. However, it's for HotA.
Also, I recently found this one; it's an old map, but maybe you haven't played it.
