1 The most important thing - the ability to rebuild the Mage Guild
2 Magic balance - unlike SoD, there are no trash magic schools. Also, spells that clearly didn't match their levels have been reweighted
3 Built 2 dwellings in the town
4 A normal starting army, i.e., the absence of 10 gnolls at the start
5 No useless skills (although one could certainly be stubbornly insistent and say that there is a certain charm to obtaining Keen Sight even in SoD)
6 Anti-cheat. Not a panacea, but still.
7 Logistics and some imba heroes have been fixed. Exception: Brogh.
8 A more normal balance of castles than in SoD. Exception: Taver.
9, 10 etc. - for those who like them - potions, disabling morale and stacks, spells, unnecessary artifacts, timers, etc..
At least the first 6 points are worth looking into. It's foolish to deny that they improve gameplay, and significantly so.
As for the rest, you're right. Driving a Lada or a Subaru is a matter of individual taste.
