Isee the major difference between this and HoMM now I feel.
It is this:
In HoMM if you f* up your party, then you can surrend, and go back for gazillion others.
Here you have to have for the whole scenario THE correct party to accumlate exp with it. If you did something wrong at the beggining, you'll have to restart from squat.

Also: although you'll be able to carry over just your only heroe, there is no chance to develop a superhero by sending 'im around without party.

My idea about different leaders:
- Warrior: you'll have a nice regeneration, so you'll have to return home less, and will be less vulnerable to surpriseattacks (or multiply attacks) from the enemy (yes, there are always enemy heroes wandering arounf like in HoMM, and here regular monsters do not spawn randomly, so exp is hard to come by, and enemy is twice as dangerous from this aspect). You'll also have abig mutha for the first row right at the start of each scenario.
- Mage: PUT HIM IN THE BACK ROW! Yes, even during the first scenario of a campaign, when only lvl2 units are avaiable so the difference isn't that great, is a nonworking idea to put 'im first line (and a party of four IS limiting). You'll have a strong, multiattack member in the back row with decent protection, and you will have to worry less about partymembers dying (most lickely someone from the first row will die, and that won't be you). The two spells per day thing doesn't seem that improtant, and not all lvl5 spells sound interresting, but casting "extra movement" and a battleboost does sound nice.
- Guildmaster: After the first week you won't know where to spend your money, so I do not recommend this. Also thieves are nice, but if you are not really into corrupting a lot, it is perfectly ok (for me it seems at this point) to just spy (required only once per race, result is being able to see the units of their parties), poison (damage without battle), and duel (against lone things, mostly rodplanting heroes).
