Ult Stacking
Overlapping Ults of the same type or role, wasting resources — and the judgment to avoid it.
The most typical "stacking you must not do" in Ult coordination is layering your own Ult onto a teammate's same-role Ult that is already active. When same-role effects overlap without adding up, you burn two players' worth of resource for one Ult's worth of effect. Conversely, the mirror — laying yours on top after the enemy commits the same type of Ult — can be an effective counter. Within Ult coordination it functions as the vocabulary for "the decision not to press", and staying conscious of stacking is the key to resource efficiency in Ult Cycle management. It demands the habit of always checking "does pressing now overlap with anything".
Before using an Ult, confirm that no teammate is already running an Ult in the same role; if it would overlap, hold it for the next engage. Also used to read the timing for laying a different Ult on top after the enemy has committed one.
Dropping a same-role Ult on top of a teammate's that is already active — two players' worth of resource spent for one Ult's worth of effect. Or the opposite: fearing stacking so much you never press, and the fight ends with Ults still in hand.
