Majesty can be fun to watch - each type of hero has a distinct personality. It's not really possible to just sit back and relax in the campaign missions, but in the freeform play? Oh yeah.
Pro tips: Paladins can be comedy gold. Rangers usually avoid trouble. Elves are just irritating. Healers are surprisingly hilarious when trolling groups of mobs at high levels.
It actually depends on the campaign mission you're playing. Evil side is much more friendly to the player micromanagement-wise - they get most their key strength from the lowest level, so if they die - you can always just recruit more of them!
Warriors of Discord are actually really good "trash" cleaning heroes - they can solve the level by themselves if you recruit enough of them. Sure, they're slow, they don't buy stuff, they're not very strong against single hard-hitting mobs... but they automatically attacks monsters and lairs, without any actual input from you in terms of rewards. And if you want to direct them, they're also very easily attracted by rewards...
I've solved the Elven Treachery with Warriors of Discord in 21 days. Could've been faster if I haven't managed to fail to spot one tavern on the side of one the little settlements. All because elves were too scared to actually fight them and were constantly running away from them.
It's actually a thing I've recently noticed - in some scenarios, with strong mobs roaming around your castle, you're better buying off heroes that are too dumb or too brave to retreat from danger (like WoDs or Solarii), or forcing your heroes into fighting - usually they do that if the monsters attack their home guild, or the palace itself (the last one makes all heroes go into "defending the realm" mode which pretty much disables retreat for them, but it requires a proper setup to really make use of, and a lot of luck to not actually lose your palace if the strong attackers come).
WoDs and Solarii have also another good quality in them - they attack lairs automatically, without having you put a bounty on them. Very useful, very economical.
(God this game was so deep in how everything interacted together, I can't believe the remakers have fucked it up so badly in Majesty 2).
