Missed the point!
The proposed abstraction is for air and convoy warfare, both wars of attrition not tactical brilliance.
Land warfare in WW2 was in many parts one of brilliant maneuvres, instead of attrition. HoI3 did it WW1-style, simply pushing back the enemy. Whichever side runs out of manpower first, loses.
Take Fall Gelb for instance: the campaign was decided by Mansteins Sichelschnitt, not attrition. A large encirclement of the enemy. Same with Barbarossa, Bagration etc.
Since air and convoy raiding are by nature wars of attrition, not abstracting them adds nothing to gameplay. Well, nothing but an array of exploits probably.
You don't have to be in favour of abstraction, but at least try to use solid arguments.
In fact my argument was only 25% sarcasm/criticism against abstraction. I am actually expecting an expansion upon the arcade mode in HOI3, where there were no supply routes. If the goal is to make the game more friendly to general public then a mode that turn a lot of things including combat, production, politics, tech, and diplomacy into abstraction (but not necessarily complete autopilot) would be nice. In fact I won't vote against incorporating the "arcade mode" in normal mode. When you have done all the decisive movements and all that's left is cleaning up you can simply switch to arcade and not bother with the huge mess of unit deployment in later stages of the game.
