Well it's not like we have much to talk until the tournament starts, so
In my opinion the game is currently the hardest it has ever been, in general. A lot of the powerful escape options have been nerfed or removed (haste, cTele, evokable Invis, even limiting evocables to a single unit of a type), and each branch has enemies that can easily necessitate the use of an escape option if your character isn't above-the-curve-OP. Combined with the shortened levels, which limit not only the experience available but the loot you can get, this results in forcing you to specialise your character a lot earlier than before.
A character which is kinda meh at two types of killing will now have a much harder time surviving until both are up and running, since for example Orc is now a ton harder for weaker characters, and you may end up rune-gated since Depths will not likely be an option.
On the other hand the game is the easiest it's ever been to start playing, so I can get behind this. There is no wand identifying minigame, no consumable destruction, no permanent corrosion, no stashing, no corpse sacrifices, food is relatively streamlined, no weight - all of these are good changes.
Still prefer Tome4's combat though. If only the expansion hadn't gone steampunk. Oh well, not like anyone's forcing me to play it.
edit - copied this in the general thread so feel free to ignore it here. Still put in too much effort to just delete it tho
