Well, played the day 0 fully patched version fpr about 6 hours, and while I'm really glad you released it, please focus on a bugs for a while!
I found oodles of them. Some easily worked around, many not.
Big ones:
1) Imbue Essence asks if I want to give up 3 essence, and then takes a lot more, probably due to my having many shards and essence towers, and so the champ is recieving 3 and getting a nice multiplier (up to 5 in my case) and so it took 5.
2) graphics getting mixed up very often. My wife turned into a different person in her circular icon, the hud for my city changed to read the city of an enemy and wouldn't fix with hide/show hud... had to build something there to fix it, one champ changed from one graphic into another guy's graphic seemingly permenantly, after about 6 hours of him looking the first way.
3) This is a big one for play: when I have a friendly stack and mouse over the circular icons, the "card" changes fine. This doesn't happen with enemy stacks in many cases (usually). The then makes me have to click on each circular icon, and then click on the big cirular picture to see stats for each enemy, which is quite painful.
4) My minor water elemental showed his 2 mana, but when he got to level 3 or 4, this hit point bar got big enough so that it deleted his mana bar from view... there seems to be no other way to check his mana amount at that point.
5) I imbued a champ with mana and she had 10 mana, when she tried to teleport it took 5 mana and did nothing.
6) This is not a bug, but may as well be: the random numbers in combat are WAY too random. Why bother with having subtle elements like 25% increases in defense on a unit when a unit with a 36 attack can easily get only 5 damage when they are in the open? Even when the enemy has low armor and is of similar level. I don't mind some randomness, but the amount here makes many of the subtle tactic simply not worth worrying about, since luck determines the battles in most cases, given reasonably non-stupid play.
7) The particle system seems to fairly quickly stop working, in random ways. On loading the game, it all works, but then random particle effects will go off and STAY off permenantly fairly quickly. By about 1 hour of game play with no full reload, no particle effects at all work, including spells, shard "rays", smoke from towns, and even the glow of adventure locations.
8) Maybe not a bug, but probably: I spent tons of reserach on getting heros and legends, and saw extremely few show up. In fact, more showed up before I invested in these technologies than after. After researching Legends, the following 60 or so turns saw none show up at all, and if it matters, my cities were big and had buildings increasing influence. I finally had one level 3 production chick show up, and made her into a mage, but the pay off was pretty slim for the research invested.
9) Alt-tab usually, but not always crashes when I alt-tab back. In battle, it happens nearly always.
10) Random crashes after fairly long amounts of play, probalby memory leaks.
Great game, but needs about 3 weeks of pure debugging, then more balance passes! Going to love it when done
