Actually, if it's possible to implement a Guild Master rework into SoD (which I highly doubt), then you can confidently play the championship on it. Because the biggest drawback in SoD (subjectively, of course) is the problem with obtaining control.
However, such a patch would ruin Warlord Tactics for everyone who isn't interested in playing with experience and mirror matches. And even the freaks in the chat won't save it.
Hota has also gone down the same path, regardless of Warlord Tactics (except for morale), which is why I believe that this is still common sense, and not someone's whim.
Guys, you'll have to stop criticizing or abandon Heroes soon anyway! This is the verdict, and seriously, your attempts to keep "full Warlord Tactics" with all its global fixes, which many players consider unnecessary, are more like the desperate gasps of drowning people. In the Warlord Tactics chat, people either come in who have been there for several years, or just to "throw in their two cents." As far as I understand, the main criterion behind your desire to play the familiar Warlord Tactics is the time saved per game. Currently, the HD mod allows you to play in exactly the same time frame as Warlord Tactics (with rare exceptions, if you don't take Warlord Tactics "experience" into account).
p.s. of course, this is just my opinion, but I think many people will agree with me. You are fixated on what you are simply used to, and new members of the Heroes community who want to participate in such events (in this case, I speak for myself) will be very disappointed that their chances of competing in the tournament will be significantly reduced due to a lack of knowledge of many nuances or simply a lack of Warlord Tactics gaming experience.
And it's funny to hear about the "familiar Warlord Tactics" - almost all top Warlord Tactics players play SoD at the same level. This is called "general Heroes skill."
