please say EXACTLY what the problem is. If you manage to make me see it too, I'll deal with it.
This is impossible to determine, because you claim there are new mechanics going into the game that makes it fair.
If this was the split in the last iteration, NA territories would be too spread out, making it hard to bring armies and gold together, while the EU territories just get to daisy-chain like a pre-industrial fire brigade.
Let me explain:
NA would actually be two halves denoted by the big blue line, these are lines which isolate territories based on the old version of strategus where you could easily transfer troops from one side of your empire to another in a matter of seconds.
This is important for two reasons: It allows you to defend with a smaller force by being able to reinforce with your entire strength anywhere in the empire. Any clan would be unable to have territory crossing the dark blue line without severe penalties to defense.
Second, it allows you to bring reinforcements to any offensives you might have to territories you have recently conquered, trying to attack over an isolation line would be difficult, without caravans of troops and equipment flowing in.
Now this map isn't 100% accurate to the strategus map, so it is impossible to judge based upon just looking at this one. In the actual Strategus map the rift between Uxhal and Dhirim doesn't exist, but the isolation zones are still true in the north, as well as in the lower eastern corner of the map.
But if chadz has magically dealt with this problem with some unforseen game mechanics and there is similar benefits to having only 36% of the map, as EU clans would be able to heavily influence NA affairs via supplying troops, far moreso than NA would be able to meddle with EU. Then this post matters little.
