I like EF and dislike blitzkrieg for some reasons and my opinion is not for combining this mods.
But...for the future....maybe developers of Eastern Front will take a look at the multitude of command points and skills from Blitzkrieg,and will give a little boost in Eastern front in that direction,in their unique stile....but not so many command and abilities like in BK...because the essence is lost in the "forest"...but much more than it is now in EF....
With careful analysis,and approval from Blitzkrieg...many new skills for units and command points,can push Eastern Front even more,in the shortest time possible, to a splendid horizon.
