I just hope that they will polish the warrior/palladin/mage skill set - I was very dissapointed by the skill selection and found at lest one quarter of the skills not very good chosen.
Would love to have less skills hard-set and having intead large variety of skills that would be optional (like in heroes of mm) - for instance I would not choose the warrior skill that reduces leadership for horsemen/ swordsmen, when I want to hire undead army only
... Or I would not want the mage skill that improves ORDER Magic (ressurections, armor of gods) - when these are not working on undead - which I have in my army...
If this was designed to make player attached towards good units/spells - it didn't work, still it took a lot of fun from the game (I had many unspent runes when I was level 30 with vampire army) - but still I would love some level-up fun...
