I'm fairly confident that the majority of NA would agree that there are too many fiefs on our side, as conflict over fiefs is what should drive most wars. Similar to RISK, the more land you have, the stronger you can become. In the current state of NA strat, all factions can stretch themselves incredibly thin, and even then have no need to fight over territory since everyone else will have more than they can manage already.
The issue is that NA strat and EU strat are tied together. If you were to chop off the entire desert and steppe from the NA side of the map in order to consolidate all the fiefs into the center region, then trade bonus would be shit and no one could get money. If you remove random fiefs spread throughout the map, then people will still have to spend days upon days marching across the map to get the full trade bonus, only now they would have fewer goods to take with them each way. Ideally, the NA side of things would have a smaller map, with increased trade bonus so that we need not travel as far to get 350+% bonus. But, since the EU and NA maps are joined quite literally at the hip, you can't simply alter the trade bonus formula for only NA. We're kinda stuck at the moment, and the only solution is to somehow separate the NA and EU maps so that they can be tailored to each region's needs.
