Because you can't organize your army. From what I've heard there is no OOB at all, so every unit will be a separate thing on the map. Sure, it will be easier for CK2/EU4 players to manage but for me it kills the whole immersion, along with the Playdough map and stupid looking counters. And inb4 "modders will fix it!" - I'd rather get a complete game at start.
Not to mention I want a game that's better than the previous one, not merely adequate. At this point I fail to see how the HOI4 combat system will be even on par with DH. What they should have done is refined the HOI3 land combat system, not just cut it out and replaced it with Arrow Simulator 2015.
this accusations are baseless...
in HOI III, as Germany, to create an army HQ to attack Poland (for exemple) you needed to select 4 or 5 Divisions, create an HQ for it, select another 4 or 5 divisions, create an HQ for it, repeat until you have 5 core HQs, then create an army HQ, then select the core HQs and attach them to the army.
In HOI IV, you select the 22-25 divisions with ONE click, "create" an army HQ (that is what it represents in this exemple), select a General, and DONE, the difference? in HOI III you needed 15 - 20 clicks, in HOI IV you need just 2-3....
..and what the Hell is your beef with arrows? how is the green doot of HOI III any better?
do you forget the frustration when the AI of HOI IIII decides to attack a major city (like Kurst or Paris) head on instead of trying to encircle it 1st!?
with arrows, you can select the path on were you want your army to go! you can decide the Border the Army should defend instead of just praying the HQ below theater would choose the Border Correctly...
you have more Controll with HOI IV then you could HAVER have in HOI III, with much more effienct AI to Boot!
