Well after seeing what happens in-game, I think when I play Germany I will simply remove all AI boosts
The problem, IMO, is that the mod forces the player too much to do historical choices. IMO as much as I like the decisions etc that the mod gives, Fernando Torres made some dubious choices about the difficulty in his mod.
"The humans play better than the AI". Sure they do. However, much of that has to do with the fact that players will play two or three times, correct their mistakes (oh why I spent so much on diplo, or why I built that) and then "power-game" - that is, make only the "best" choices. For example, you simply didn´t use intel or other fancy options like wargames, and instead used Money elsewhere, and used a rather standard build. That is bad gameplay balancing, and its why I like Ironman mod for EU 4. You make mistakes and move on, and there is no "best" way to play. Here, you play a country two or three times, find the optimal path, and only use it.
IMO normal should be that, normal (and thus allow the player to follow many paths), and Hard and Very hard be focused on veteran players. As it is, it´s simply impossible to do ahistorical stuff in the mod, or even use other paths.
On the other hand if you do accomplish a Seelowe or invade SU from Turkey I will be impressed and accept my noob status
