Bits of Beta feedback:
I missed the line in the patch notes about the AI upgrading outposts and was very excited the first time I saw an updated one. It was a surprisingly big deal to me, as is the fact that in my 1.6 and 1.7 games the AI players are using strategic spells, which they didn't last time I played. Makes steamrolling with a single army a lot harder.
The wildlands monster spawning has been interesting. They seem to pop up in occupied areas quite a lot, or at least within a tile or two of my outposts, quite far from the wildlands. This could get frustrating if the difficulty in clearing wildlands isn't fixed (in a 1.6 game I couldn't clear the Imperium or the swamp but could clear Abeix's wildland, in the current game I have managed to clear Vetrar and Abeix's wildlands and haven't had a chance to poke around the Imperium yet). I'm mainly seeing crow demons and lone darkling shamans, at a point in the game I have longsword and heavy armour-equipped troops, so maybe the parties need to be stronger but more controlled in where they spawn.
The bug with multiple copies of unarmed heroes being spawned by the wildlands could be refined into a neat feature - some tough heroes allying themselves with chaos rather than order and leading monster parties in the late game?
A couple of other points...
A few old problems are still around - the AI will pick a poor quality location to settle instead of a superior one right next to it, player-controlled cities still lose defenders if they are attacked more than once on the same turn, and defeated units still sometimes complete their moves after dying, destroying improvements and outposts I was trying to protect, even if paralyzed.
One I haven't seen before - I was attacked by Vetrar and, after losing my hero and half the army to one blizzard, hit autoresolve in frustration and found that my remaining units had somehow vanquished him (that hero has since been knocked unconscious in three or four other major engagements I have gone on to win, including one against Bonesplinter that has led to him riding around on the beast that horribly maimed him, so I like to think it has become a running joke for his men). The units were a group of four with shortswords and chainmail and a group of four with warhammers and leather, so I don't think it's working as intended.
The strategic version of wellspring doesn't seem to work - it deducts mana but doesn't heal my troops at all.
Doublestrike (I think) seems to be able to hit at range even when the AI character is using a melee weapon - axe-wielding Verga hitting my archers from across the battlefield.
On the dialogue side of things, there's a couple with small spelling and grammar mistakes but also some that just don't make sense - for example, an AI sovereign will pop up and just say 'Let us speak frankly', with the only response being 'ok'. Most, however, are great - especially the 'annoyed' version of throwing an army out of their territory for the third or fourth time (is that new?), and any time Magnar threatens to enslave my troops.
In tactical battles, AI archer units will sometimes group up on the same tile as each other - retreating into an occupied tile and then firing.
Think that's all for the moment.
