If you are an ordinary player, sitting with a beer and clicking the mouse, then these classes, monster experience, and precise knowledge of which conserve can be taken with which forces from each Castle are simply not needed; it's just extra stress. Why bring TE closer to SoD? Most casual players are quite satisfied with the current state and will stick with pure SoD, while those who play TE would prefer it to be even further away from SoD.
Then, to reduce the stress even further. Even beer won't help you relax when you have to constantly click back and forth. I repeat, the idea is not to implement TE, but to make the game more convenient and faster. Often, all the time of a turn (4 minutes) is spent only on transferring troops and splitting them into individual units.
Ah, yes, probably true relaxers don't split armies into individual units and play with 2-3 heroes. They don't need this infamous Button either. :D Well, this game is really not designed for such relaxation. Moreover, I am sure that such players do not post their games in reports. They don't need it. They play for themselves with a beer, lose in conserves, reload, and continue. I am not blaming them in any way – it is their right to play that way, please, go ahead. But if a player is even a little interested in competitive spirit and the desire to climb higher in the table, he will already build hero chains skillfully, split armies before taking conserves, and it will already be difficult for him to play without the Button. In addition, there are features in TE that even SoD players might appreciate. The vote will put everything in its place.
