Is diplomacy necessary?

Diplomacy on a map with many castles and opponents is simply essential (you need to keep someone in the castles for defense). For Inferno heroes, it increases the number of fleeing creatures: what's wrong with that, especially since the commander's specialty is that?

It's not a given that there will be the right creatures near the castles, and it's not necessary that there will be enemies near neutral castles (especially if there are many castles). In the early stages, mega-units won't join, and a bunch of weaklings will ruin the morale, even in the castle, and in the later stages, even stronger enemies might appear; they will kill that unit in the castle, even if it's a strong one... they might kill it, and by that time, you can build a castle: it will be better for defense...
