LeBron, I'm afraid you misunderstood the question slightly. What will be the fundamental difference for playing Heroes specifically on those templates being offered: Jebus Cross, 8mm6, Spider? Although for Jebus Cross, I agree, the starting army and especially a built-up level 2 are of significant importance. But for 8mm6 it doesn't exist, or rather it's not as significant as for Jebus Cross. Roads, of course, being fast is nice, but for example, I also like to play on slow ones. It does take more time, though. As for transferring troops, it doesn't matter what map size you play on, whether it's 8-10 heroes on L or XL.

I understood the question exactly :) specifically THOSE and specifically on MM6
Logistics. You can run through the entire SM in 3 days—so the speed coefficient on the road isn't as important here. The MM6 map is played on XL: now imagine the situation: you have 2 Dragon Utopia at opposite ends of the map that need to be taken in 1 turn—the roads are slow—how many "loshkis" do you need to transfer the army and artifacts from one part of the map to another? 15-16, I think... so in the best case, you'll spend 3 days moving the army without Town Portal and Dimension Door. From this, we conclude that the game is dragged out MANY TIMES over just because of the speed on the roads
For the same reason, the speed of transferring the army is important; on MM6, where you have to transfer the army from side to side every turn, it can extend real game time by many hours
Dirty already mentioned classes and guild rebuilding
P.S. there was an MM6 tournament on SoD on the portal—if anyone is interested, go read about games lasting 16-20 hours ;) still want to discuss SoD for MM6?

And experience isn't that important IMHO

I categorically disagree! Even playing SoD on SM, in many games you have to take difficult objects like cons 3-4 or max nagabanks with "loshkis" in the second week—with experience, you can take even more difficult objects at even earlier stages, which will further speed up the game—and I repeat again, this is VITALLY IMPORTANT for MM6—because the main problem of the template is the time per game
