Should I split my units into smaller stacks? (Ranged vs. Melee)

Splitting ranged units can be beneficial because each separate army fires on its own attack cycle, allowing you to produce more attack ticks and control splash damage more effectively. This gives you greater tactical flexibility as you can increase your total damage beyond the 50-unit cap.

Splitting melee units, however, is usually a disadvantage. Smaller melee armies take proportionally more damage from enemy retaliation and splash damage, since every nearby army pulled into splash radius retaliates. This makes split melee groups die much faster compared to one consolidated melee force.
