Mass fight is a way to kinda raise Stakes on story but current game mechanics and combat designs feel slightly unbalanced.

Encounters could Be "smaller sized but having soldiers and armies on backgound would be better
to have multiple smaller encpunters. Currently I'm waiting minutes to Make Ai resolve their turns when as BG player (rts Gamer would want to act as soon as possible) not blamign or requesting real time just I want have faster way to get to turns.

Less HP \ soldiers would improve attack impact on strikes. D&D encounters tend to Be slightly easier than your standard larian Divinity design, Having too Gard fights take Focus away from actual story beats.Alternatively some magic wands or spell scrolls with proper spell Power would give more options to handle mass Encounters on offence fashion.

Pros & Cons of Combat
+ ways to interact with environment.
+ Storywise big impacts
+ Small enconters are interesting

Cons
- Too long to wait your turn only to miss an attack.
- Way too much HP \ creature with overwhelming numbers.
- Lack of proper def options to prevent 1 shot attack mass "targetfire your guys down randomly."
- Encounters are slightly too "hard" about 20%
- lacking proper means to tip battles to your favor.
