my favourite take on this is to have characters fighting in groups, then it becomes obviously necessary to call out moves so others know what’s going to happen and can know to not stand on the other side of the enemy that’s about to be showered in flame.

it also makes a nice contrast between solo fighters and those who simply don’t care about collateral damage: some villains can be pure chaos, you can have rogue heroes who just end up hurting innocent people because they don’t coordinate, and villains who do coordinate will look way more threatening because they aren’t hurting themselves.
