While I don't like some parts of Unfair (mostly, the Prologue with too much RNG dependency), some parts I'm growing to appreciate. Fights vs more difficult opponents turn into puzzles, rather than being copies of themselves (maybe this will change later, I don't know). I can only compare what I'm seeing to my previous runs through Chapter 1 on first Normal and then Core. Fights as puzzles is something I appreciate in cRPGs, it's been that way since playing BG with SCS, and then Larian games.
Take the Tavern Defense battle, for example. Previously, I had to learn the basics, but once I got them, the fight went alright no matter if I placed/moved my characters ideally. Now with Unfair, I had to redo the fight at least 10 times. Step by step learning what to do during wave 1 (how to evade Stinking Clouds mostly), then how and when to move to better placements for wave 2, and then, of course, wave 3. For example, I learned that I need to move at least 2 characters to the spot where the second wave arrives earlier, to handle a single alchemist there. Or how to buff 2 characters (the leopard and my duelist) during the first stage before the horde reached them.
I actually found the key to the Minotaur by accident, using an Expeditious Retreat scroll for better mobility throughout the fight. And it so happened that the Minotaur started to target my main character, who was under the effect of that additional speed. I just kited the bull around while my characters kept hitting it with attacks of opportunity.
So the Tavern combat really opened up on this difficulty setting. It wasn't just "keep spamming Grease/Winter's Grasp" at choke-points. I felt the need to constantly move characters around in reaction to the stage of the fight, which reminded me the RtwP genre comes from RTS games.
We reached lvl 5 just after the fight (very lucky, it was 12040 xp when the threshold was 12k), and I picked Expeditious Retreat for my sorcerer, along with Mirror Image. Let's see if these tactics will be of use at any other future point.
Also, noticed just now that my bard picked Bardiche instead of Fauchard due to my mistake, but I'll stick to this. I haven't used bardiches either, so I guess the meta-game choice of fauchards will have to wait longer (previously, I only tried glaives in WotR).
