On that front, they stayed true to tabletop. Cause I remember when I was playing DnD, if I hadn't told the DM I had cast mage armor in the morning, when a fight was breaking, he was reminding me that as I didn't tell him, it meant I forgot to cast it :P
And as well, squishy mages being targeted all the time, well, that's also what basically happens to you when you start a new D&D campaign as a mage. Positioning and preparation can save your life.
Also true, totally kill the heals and mages first; however, that's what mediocre DMs do. not all creatures will know to kill the healer or mage first. Even some goblins have no clue. you can hear as much when you go to the goblin camp and overhear them talking about healing magic as a foreign concept. I don't want to be too hard because over all i love the game and these are things they are still working on. I just want to see some of this stuff implemented because it's fun and improve QoL.
also i know it's a game AI not a real DM so my hopes aren't incredibly high on that front and by that nature it will be more like player vs DM rather than the DM trying to build a narrative through combat. but this is the best time to put out feedback.
