I'm going to reroll for the 3rd time and take my min-maxing even further too. From some more experiment, even if you do spec into Wit, the game now forces you to act in rotation so even if your wits are insanely high, your enemies will also get to act.

This means you now only need one char with a seriously high wit for the first strike. The rest just needs their wits to be above certain point to get them to act in order and you can spec into pure damage right after that.

Tactician mode is more like Cheese mode now. You have to savescum before opening any chest just to make sure you get the right magical loot you can use or you're going to have a very difficult time with cheap overbloated fights.
