2asm:
Simultaneous turns would completely change the game and turn it into something else. And the game would lose more than it would gain from this.
And the "evolution" in the form of WoG (TE) also rather repels. An example of this is heroes.by, which is dying precisely because of TE, IMHO.
To retain and attract people to the game, TE should be brought closer to SoD, and not moved further away. It is possible to limit oneself to useful "features" such as quick army transfers, separating individual units, etc. Saving replays of battles would be a very useful thing! But classes, changed secondary skills, specializations, magic, etc. - this is not what we should strive for!
