When you balance enemies for the WotR have something in comment.
In both real time combat and turn based combat, spellcasters are underwhelming as they require of much more micromanagement than fighters. I think that many people here, we use spellcaster either for healing or haste/slow.
There are few ways to go around that, one of them is making less combat but more challenging.
But what does not help at all, is the fact that the “bosses” have a ultra high spell resistance/savign throw. This makes sense in tabletop as in tabletop the micromanagement of speelcasters is not an issue, but it is an issue in the main game.
Now i am fighting the boss of the dungeon DLC and octavia is like … well, anyone has a beer? because it will never surpass the saving throws of the enemy,
