1) How the hell do you cast a spell not in combat?
2) How do you advance in one type of spell casting? I only ever get offered level 1-2 in a few areas to learn. Is this really that random? I have 5000+ mana and can't see how to use any enchantments except combat spells.
3) Can you bring back the hero stat distribution system from EWOM along with this new skill system? I would like to distribute maybe 2 skill points a level and learn a cool new trick too.
4) Can't say that I see how the research point qty/level system works either, I mean I have some cities and some libraries etc but I need to see how this works or if it can be spelled out somewhere then I could leverage this perhaps. seems vague.
5) Crashes in combat when you fight the little grey dudes and bears almost 100% of the time if they close within melee range. Also Principee has the same issue, you have to mow her down before she gets too close.
6) AI spell casting is usually defensive... have yet to see a single offensive spell used against me aside from one Empire Champion I killed used burning hands on me, once... this lets me kill them usually by the end of turn two in combat.
8) AI armies. I've killed dozens of stacks of armies that are really crap units. I mean 20+ groups of 7 units that are all unarmoured spearmen & archers in one square. My one group of heroes killed them all in a few turns. Maybe if you are defending you can have up to 3 or 4 piles of 7 units in the battle against the attacker... or something.
9) Heroes, if some could randomly enter the game later (maybe they do I just didn't play that long maybe...) that would be an awesome addition to the current way you find them. Or maybe you have to build a particular building in your capital to start this?
1: Made some screenshots for you!

Follow the big red arrow!
the spellbook button in the main game is HIDDEN in the bottom right corner next to the End Turn button (though they could be larger, agreed)

Example Spellbook, notice the big red ring notifies a "next page" button, and the blue is where the "previous page" would be! (Posted this one because those page buttons are damn hard to find!!
2: This is one of my main concerns about leveling, wonky choices and never the ones I like. I hope they modify this to be a little easier, since I like focusing on heroes.
3: I haven't played AWoM, so I cant argue about that, personally I think the stats should poof up slowly with lvling, either by choice or by automatic, though not so much you get super-powered heroes (gonna make a post about what I think they should do with heroes).
4: seems fairly simple to me, let me try to explain it:
each turn, you gain research points equal to your citizens divided by 10 (calculated in each city), this is modified by unrest, and stuff like school and library,
when you have all that research, you may add +2 from scholar champion ability, or any other champion ability gaining research points,
when that is added, add +10% if you are the faction that gains +10% research or subtract 10% research if you made a faction that have a penalty to research.
5: I don't have a lot of crashes in combat, actually the crashes I have seem rather random (1 crash when saving, next crash would be when starting a combat, next crash would be when creating a city with a pioneer). I haven't seen any persistent crashes that included Little Grey Midgets or Bears or Principee.
6: AI spellcasting needs work, though I usually se them casting curse or whither if they have them, probably just by chance you meet all the defensive heroes, though I agree they should stop when in melee range, and remember to move before casting spells (according to how many spells they wanna cast, and if they are to be charged in a moment, and move forward if you have archers, etc.)
8: There have been alot of threads about AI behavior, especially with theyre armies of meager peasents, and when they decide to attack you with wave after wave of pioneers. Though I feel there is a problem with the AI Being Able to stack theyre units, since I am having a hard time stacking mine.
9: Great idea! (especially for lvl 9 heroes). Also having some heroes wander (meaby even at certain speeds, so they won't all just be rushing around the map). But details like this I feel will be down-prioritized until they got a proper game working
