I never played the game (both vanilla or any mods) during WOI because this aspect is not interesting for me. Thus, I could be wrong. If I understand correctly the problem, the Royal Fleet during WOI appears in very predictable tile (or tiles?) and you plan to change it. One of variants is Well, if you like to implement by such way, please, do it. I have nothing again. However, I'd like to mention that the geographical position of two points (Europe as a starting point of King Fleet, and your colony in New World as a final point or a "target" of the Fleet) are the same all the time during the game. Thus, the Royal Fleet during WOI should appear all the time practically in the same region (+/- 5-20 tiles from some middle (X,Y) entrance point depending on map size). Sorry, but I cannot image how the Royal Fleet sent by your King from Europe in New World (let's say in Caribic region) can appear from North or South Poles, or from the West (I suppose from Pacific Ocean). It's nonsence, to my opinion. Probably, I'm wrong because, I repeat, I never played during WOI and don't know all features realated to the King Fleet. OK! It could be deactivated, if really "variance between North / South but even East / West" will be implemented. 100% support from my side. I really like this idea.
