Funny discussion :)
I don't remember how many kilobytes Might and Magic takes up; it's quite a lot. And I assume that a Heroes player of average tournament level knows about 80% of it, if not more. And good players know 95-99%.
Heroes is a game with a very extensive body of knowledge, which you need to know as much of as possible and remember as quickly as possible to play effectively.
Therefore, reasoning that it's difficult for some people to remember what 10-20 checkboxes mean... you're not working with an intellectually challenged audience... it's logical to assume that the reason lies in something else.
I would also like to note that for many years now, all attempts to create hybrids of SOD and TE/WT, both in terms of engine and rules, have ended up in roughly the same way: 1-2 tournaments are played, after which people scatter back to their own sandboxes. This also encourages reflection.
I'm saying all this because before suggesting something, it's advisable to analyze the situation. Then there will be fewer "we were going to do this, but it turned out like that..."
What does Might and Magic and other things have to do with it? What are you even talking about?
This checkbox won't diminish the TE players, but it will be a plus for the SOD players. There's no need for any populism here.
