2. Territories that are split: Imagine a player is looking at the bottom half of Elets-Don. They would have no way of telling that it also connects to Kasimov-Oka, since they don't even come close to touching. Split territories should be split into two seperate territories, or the map must be changed to show that they're one territory.
Just curious,
why is Elets-Don even a single territory? Maybe I'm missing something, but it seems really counter-intuitive to me.
Note that Fizzer didn't say split territories are prohibited, just that players should be able to easily
see they belong together. For instance, in the case of multiple islands together being a single territory, this is commonly done by drawing dashed lines between (or, for a larger group, around) them.
While this trick won't work in your particular case, I hope now you understand what the issue is exactly.
In the similar case of Carnobyl'skaja, you might want to consider removing the "corridors" of the other territories between the three pieces of Carnobyl'skaja and make it a single, contiguous area. Also, consider getting rid of the enclave of Mogilev. (Fortunately, neither of those modifications would change which territories actually connect to which neighbours.)
While I appreciate many map makers take great pride in the accuracy of their maps, please consider this: you're making a map to play WL on; you're not making a map for geography class... If accuracy gets in the way of playability, wouldn't it make more sense to sacrifice a little accuracy (and maintain ease-of-play), instead of rigidly adhering to accuracy (at the cost of people having to play the map a few times before they even know how it works)?
I like playing beautiful maps, but not when I have to double-check for weird connections, multi-part territories and/or non-contiguous bonuses (to name a few of my personal dislikes) on every single turn.
Hope this helps,
